  1. Black Sea

  2. Red Sea

  3. South China Sea

  4. Arabian Sea

Show answer
Correct Option: D
Explanation:

South-West monsoon has two branches, 1. Arabian sea branch, 2. Bay of Bengal branch. The moisture ladden winds of the SW monsoon follow the path of low pressure zone so as to reach ITCZ which is at ganga plains due to northward march of Sun over the tropic of cancer. While flowing towards ITCZ the Arabian Sea branch gets obstructed by the Western ghats, this gives heavy orographic rainfall on Western coast. On the other hand the bay of Bengal branch flows parallel to eastern ghats, so there is less precipitation.
