In March 2015 the United Nations decided to increase Pakistan’s Continental Shelf from 200 to 350 nautical miles. When did Pakistan submit its request for increasing limits of its Continental Shelf to the United Nations?

(A) April 2009
(B) October 2010

(D) January 2012

The formal claim was filed by Pakistan with the United Nations Commission on the Limits of the Continental Shelf (UNCLCS) on April 30, 2009, for an extension of its continental shelf. This claim was based on the four-year technical study, which started in 2005, conducted by the Pakistan Navy in collaboration with the National Institute of Oceanography. After thorough evaluation, the UNCLCS approved the recommendations in March 2015, expanding the limits of the sea from 200 to 350 nautical miles, adding 50,000 square kilometers to the territory of Pakistan.
