Who's realname is saravanan?

Surya, a prominent Tamil actor, is indeed the correct answer to this question about Tamil cinema real names. While the question contains grammatical issues (missing apostrophe in 'Who's'), the core fact being tested is accurate. The other options - Vikram, Vadivelu, and Nakul - are also Tamil film industry personalities, but Surya is specifically associated with the real name 'Saravanan' as claimed by the quiz.
