B) β-diketone
C) β-ketoester
D) α,β-unsaturated aldehyde
E) β,γ-unsaturated aldehyde
α,β-unsaturated Aldehyde
An organic compound with a double bond between the alpha and beta carbon atoms and a carbonyl group at the alpha position.
β-diketone
A class of organic compounds containing two keto groups (C=O) attached to adjacent carbon atoms.
β-ketoester
A compound containing a keto group (=O) and an ester group (-COOR) separated by a carbon; it's a versatile intermediate in organic synthesis.

Final Answer :
D
Explanation :
When an aldol is dehydrated, it results in the formation of an α,β-unsaturated aldehyde or ketone. This occurs because the elimination of water leads to the formation of a double bond between the α and β carbon atoms of the original aldol product. Choice D, α,β-unsaturated aldehyde, is the most specific answer.
