44AA, deals with whether Books of Accounts are Required to be maintained or not.
SSo if the Accounts are liable for Audit u/s 44AB, then one has to put a tick mark on Books maintained u/s 44AA
44AA deals with maintainence of books whereas 44AB deals with tax audit. As far as 44AB is concerned. I.e. when 44AB is applicable, automatically 44AA is applicable. And so you need to tick 44AA as yes, books are liable to be maintained.
But there are possibilities where even if 44AB is not applicable, 44AA still maybe applicable.
