Section 372A deals with inter-corporate loans and investments. So it will not apply to this case.
It also does not amount to giving loan or guarantee or security under Section 295.
You say "company also given some security to Mr.A". I suppose you are talking of advance amount.
I think this transaction is a related party transaction attracting provisions of Section 299, 300 and 301 inviting disclosure of interest by director, absenting from board proccedings and entry in the register of contracts.
