Verified by Experts

The correct Answer is:
A
`H-overset(H)overset(|)(C)=O+NH_(2)OHrarrH_(2)O+H-overset(H)overset(|)(C)=N-OH`
HCHO does not give aldol condensation.
To each with `NH_(2)OH` reactant shouuld contain carbonyl group, while not to undergo aldol condensation reactants should no contain `alpha-H` atom.
