The last time India won a Gold Medal in the Olympics was during the Moscow Olympics held in 1980. Here`s a breakdown of the options for better understanding:

Option 1, Montreal (1976), is not correct as India did not secure a Gold Medal in this event.

Option 2, Moscow (1980), is indeed the correct answer. India`s Men’s Field Hockey team brought home the gold medal in these games.

Option 3, Los Angeles (1984), is also incorrect. India did participate but unfortunately, did not win a gold medal.

Option 4, Atlanta (1996), is not correct either. Again, while India did participate in these games, they did not win a gold medal.

Please note that although our hockey team had won the gold in Moscow, Indian individuals and teams have also achieved commendable feats and won medals in various sports in the subsequent Olympics.
