Which among the following is oceans is the largest consistent contributor to the global ocean warming trends in last few decades?

Answer: [A] Indian Ocean

The Indian Ocean has been warming at a rate faster than thought before (1.2 deg C during the past century). It is also the largest consistent contributor to the global ocean warming trends. Recent studies show that a warm Indian Ocean can in turn modulate the Pacific conditions including the El Nino events. So basically, such large warming over the Indian Ocean has implications on the global climate.
