The correct answer is (c) Ind Arc.
Ind Arc is a multi-purpose underwater observatory deployed by India in the Arctic region of the North Pole in September 2020. It is the first of its kind in India and is designed to study the Arctic environment and climate change. The observatory is located at a depth of 3,000 meters and is equipped with sensors to measure temperature, salinity, pressure, and other parameters. It is also equipped with cameras and other instruments to study the marine life in the Arctic.
The observatory is named Ind Arc because it is an Indian Arctic Research Programme. The programme is a collaborative effort of the Indian government, the Indian Space Research Organisation (ISRO), and the National Institute of Oceanography (NIO). The programme aims to study the Arctic environment and climate change and to develop technologies for sustainable development in the Arctic.
The other options are incorrect because they are not the names of the Indian Arctic Research Programme.
