Explanation:

Only statement 3rd is incorrect.

• Famous Italian merchant and explorer Marco Polo had visited the temple. Marco Polo, during his visit to the Kakatiya Empire, allegedly called the temple “the brightest star in the galaxy of temples”.
• Temple was built during the reign of Kakatiya empire.
• The foundation of the temple is built with the “sandbox technique”. The flooring of the temple is granite and the pillars are of basalt. 
• Sandbox technique involved filling the pit — dug up for laying the foundation — with a mixture of sand-lime, jaggery (for binding), and karakkaya (black myrobalan fruit) before the buildings were constructed on these ‘sandboxes’.This technique acts as a cushion in case of earthquakes. 

Hence option 2nd is correct.
