(a)
Interpretation: The product that is formed by the intramolecular aldol reaction of the given dicarbonyl compound followed by dehydration is to be drawn.
Concept introduction: The aldol reaction that takes place within the same molecule in the presence of strong base is known as intramolecular aldol reactions. This reaction generally takes place within the dicarbonyl compounds in which one carbonyl group forms the enolate ion that acts as a nucleophile and the carbonyl carbon of the second carbonyl group acts as an electrophile.
