Whether sec. 44ad is applicable to function hall for 16-17ay

Yes. Eligible Business

yes it is applicable.

I think big no, because it is purely service oriented

not done any activity of trading

@ thirumalai.... it is nowhere written in sec 44ad that only trading business come under this section. so you need to read this section again.

Here business consider as only a trading line

i would again say that you need to read your answer carefully. you did a good job doing copy-paste but forgot to read that it mentions "the new section applies to any retail trade or civil contruction or any other business.
Here, it includes word "any other business" which includes services also. However this section does not include professional income.
