Does anybody have official answer keys for XAT previous year question papers? For DM section, there is variation in the answers of various coaching institutes?

Noted. Any other source which you can recommend?

I am referring to fundamakers. But again I cross verify from different sources

I dont think one existed before the test went online. I too have been having the same issue for XAT papers before 2019. It is frustrating how even some of the big institutes are given conflicting answers based on fallacious assumptions. Having said that, Ive found cracku's answers to be matching the majority other institute's answer; but more importantly the logic they give for their answers is more than satisfactory and leaves no scope for doubt.
