The correct answer is D. Discus Throw.
Vikas Gowda is an Indian track and field athlete who competes in the discus throw. He is the first Indian to win a medal in the discus throw at the World Championships, and he has also won gold medals at the Asian Games and the Asian Athletics Championships.
In the 2013 Asian Athletics Championships, Gowda won the gold medal in the discus throw with a throw of 65.26 meters. This was his third consecutive gold medal in the event at the Asian Championships.
The other options are incorrect. Long tennis is not an event in the Asian Athletics Championships. The 400 meters running race is an event in the Asian Athletics Championships, but Gowda has never won a gold medal in this event. Shot put is another event in the Asian Athletics Championships, but Gowda has never won a gold medal in this event either.
