Q. Which of the following are Indian research stations currently active in Antarctica?

1. Maitri
2. Dakshin Gangotri
3. INDARC
4. Bharti

Select the correct option from the codes given below:
Answer: Only 1 & 4
Notes: Dakshin Gangotri, India's first base in Antarctica, was decommissioned in 1990. Maitri (since 1989) and Bharti (established 2013) are the only currently active Indian research stations in Antarctica. INDARC is located in the Arctic region, not Antarctica. Thus, only Maitri and Bharti are active Indian Antarctic research stations at present.
