Aldehydes that lack alpha hydrogens, such as benzaldehyde or pivalaldehyde (2,2-dimethylpropanal) cannot form an enolate and thus do not give a positive Fehling's test result under usual conditions
hence option D is correct

Aromatic aldehyde ie, C6H5CHO are not able to reduce Fehling's solution but it gives Cannizaro's reaction with alkali.
