Explanation:

Recently, Union Minister for Road Transport and Highways has initiate the first blasting for Zozila Tunnel in J&K.

• The tunnel will provide all-weather connectivity between Srinagar valley and Leh (Ladakh plateau) on NH-1, and will bring about an all-round economic and socio–cultural integration of Jammu & Kashmir (Now UTs of J&K and Ladakh).
• It involves construction of a 14.15 Km long tunnel at an altitude of about 3000 m under Zoji La pass (presently motorable only for 6 months in a year) on NH-1 connecting Srinagar and Leh through Dras & Kargil.
• It is one of the most dangerous stretch in the world to drive a vehicle & this project is also geo-strategically sensitive.

Some of the important passes of India

• Photu La – Zaskar Range
• Banihal – Pir Panjal Range
• Zoji La – Great Himalayan Range
• Khardung La – Ladakh Range

Hence option 4th is correct.
