The given reaction is a condensation reaction between benzaldehyde (\(C_6H_5\)CHO) and acetophenone (\(CH_3CO\)\(C_6H_5\)), known as the Aldol condensation. This reaction proceeds under basic conditions (in the presence of \(OH^-\)) and at 293 K, forming a conjugated enone product.
The product formed is stilbene (\(C_6H_5\)CH=CH\(C_6H_5\)), which is an $\alpha$,$\beta$-unsaturated carbonyl compound.
Thus, the correct answer is Option (A).
