(a)
Interpretation:
The major product of the reaction is to be predicted.
Concept introduction:
Grignard reagents and alkyl lithium undergo direct addition to α,β-unsaturated carbonyls. Along with the direct addition product, they also produce a minor amount of conjugate addition product. Alkyllithium reagents generally have a greater tendency toward 1, 2-addition to
