(A) The reaction is an intramolecular aldol condensation. $1$. The base $(OH^-)$ abstracts an $\alpha$-hydrogen from the ketone group to form an enolate ion. $2$. The enolate ion attacks the carbonyl carbon of the other ketone group to form a cyclic $\beta$-hydroxy ketone. $3$. Upon treatment with acid $(H^+)$ and heat,the $\beta$-hydroxy ketone undergoes dehydration (elimination of $H_2O$) to form an $\alpha,\beta$-unsaturated ketone as the major product.
