Explanation:

 The Indus Valley Civilization was an ancient civilization located in what is Pakistan and northwest India today, on the fertile flood plain of the Indus River and its vicinity.

• Some of the important India Valley sites can be traced as:
• Banawali - It is an archaeological site belonging to Indus Valley Civilization period in Haryana. Also referred to as Vanavali, it is on the left banks of dried up Sarasvati River. Hence pair 1 is correctly matched.
• The excavations have yielded a three-fold culture sequence:
• Pre-Harappan (Early-Harappan)
• Represented by the existence of well-planned houses and a fortification wall made of molded bricks.
• In the pottery of this period, pre-Harappan painted motifs tended to become simpler sparse and use of white pigment becomes progressively less popular.
• Harappan o marked by the presence of a well-planned fortified township laid in a radial pattern.
• The sophisticated red ware decorated with animal and floral designs comprises dish-on-stand, 'S'- shaped jar, perforated jar, vase, cooking handis, beaker, basin and goblet etc.
• A terracotta plough model is important as it is a complete specimen found so far in Harappan Culture.
• Other remarkable finds are beads and bangles of semi-precious stones, terracotta and shell, chert blades, weights and sportsmen of ivory and bone, beads and foil in gold, charred barley grains etc.
• Bara (post-Harappan)
• It is represented by the most distinguished pottery, which is sturdy and heavy, made of fine clay, baked carefully and dressed with deep-toned oily gloss.
• Kalibangan - It is an ancient town located on the banks of the Ghaggar river in Rajasthan. It literally means 'black bangles' which it derives from the dense distribution of the fragments of black bangles which were found at the surface of its mounds. Hence pair 2 is not correctly matched.
• It has relics of both
• Pre-Harappan settlements from the 3500 BC – 2500 BC
• Harappan settlements from the 2500 BC – 1750 BC, but also the
• The excavation of this site proves that a well - established lifestyle existed before the Harappan civilization in India.
• It was also discovered that for the ceramic industry, Rajasthan was a significant center.
• The pottery of this place has similar designs with those of the Harappan civilization.
• The excavations at Kalibangan revealed Harappan seals, human skeletons, unknown scripts, stamps, copper bangles, beads etc.
• This was also the site of discovering the most primitive ploughed field that dated back to 2800BC.
• In 2600 BC, the first archaeologically recorded earthquake took place at this site, which marked the end of the Pre-Harappan Civilisation
• Dholavira - It is an archaeological site in Kutch District of Gujarat. Hence pair 3 is correctly matched. 
• The city of Dholavira was found to be very well-planned, divided into three stages to form a layered city with a lower town, a quadrangular middle town and a citadel.
• It was famous for water conservation techniques such as rock-cut wells and is possibly the earliest example of rock-cut wells.
• One of the unique features of Dholavira is that, unlike other Harappan cities like Harappa and Mohenjodaro, the city is built almost exclusively of stones instead of bricks.
• Shortughai - It is located in the Amu Darya (Oxus River) valley, in northern Afghanistan. There the remains of a small Harappan colony, presumably sited so as to provide control of the lapis lazuli export trade originating in the neighboring city of Badakhshan. Hence pair 4 is correctlymatched.
