Statement (A): Chola temples were the hub of religious, social and cultural life. Statement (B): Chola bronze images were of deities but sometimes also of devotees.

Chola temples were indeed centres of religious, social, cultural and economic life — they housed schools, hosted festivals, and were important administrative units. Chola bronzes are world-famous and depicted deities, and sometimes devotees as well. Both statements are true. However, the existence of bronze images of devotees is not the reason temples were hubs of social life — they are independent facts. Hence both true but B is not the explanation of A.
