Phenol on reaction with **Zn dust** gives:

ABenzene (deoxygenation — Zn reduces -OH to -H)
BCyclohexanol
CBenzaldehyde
DAnisole
Answer & Solution
Correct answer: A. Benzene (deoxygenation — Zn reduces -OH to -H)
Phenol + Zn (heat, distillation) → benzene + ZnO. Zn dust strips the OH off phenol — useful in structure elucidation of aromatic compounds. (Strong reductive deoxygenation.)
