• It was abandoned in 1988–1989 after it was submerged in ice and was finally decommissioned on 25 February 1990, subsequently turned into a supply base.

• The Indian Antarctic program began in 1981, and it has built three permanent research base stations in Antarctica, named DakshinGangotri (1983), Maitri (1988) and Bharati (2012). As of today, Maitri and Bharati are fully operational.

• The continent of Antarctica, the fifth-largest in terms of total area, covers a significant part of the Antarctic region. It is a cold terrain, located in a remote area in the Southern Hemisphere covered by the Antarctic Convergence – an “uneven line of latitude where cold, northward-flowing Antarctic waters meet the warmer waters of the world’s oceans.”

• The National Centre for Polar and Ocean Research (NCPOR), Goa—an autonomous institute under the ministry of Earth Sciences—manages the entire Indian Antarctic program.

Hence option 2nd is correct.
