D. a phenol

Answer

B

Explanation

`underset("Acetaldehyde")(CH_(3)-overset(O)overset(||)(C)-H)+CH_(3)-Mg-l`
`{:(" "O-Mg-l),(" "|),(to H_(3)C-C-H),(" "|),(" "CH_(3)):}`
`{:(underset(-Mg(OH)I)overset("Hydrolysis")toH_(3)C-underset(CH_(3))underset(|)overset(OH)overset(|)C-H),(" ""Secondary alcohol"):}`
