Which one has low latency for server in India, UDP or TCP???

Depends on what you are trying to achieve. Generally said:
TCP is slower, but it ensures that all data reaches the target in the same order (important in e.g. a turn based game)
UDP is faster, but data can be lost or arrive in the wrong order (better for e.g. player movement)
