Action of hydrogen iodide on anisole gives:

Aphenol and iodomethane
Correct Answer
Biodobenzene and methanol
Cphenol and methanol
Diodobenzene and iodomethane

Solution

Anisole on reaction with HI gains H+ and forms methyl phenyl oxonium ion.
Because of resonance, there's some partial double bond character between oxygen and carbon of benzene ring.
Thus, it's much easier for I- to attack $$O-CH_3$$ bond than $$O-C_6H_5$$ bond.
Hence, anisole reacts with HI to give phenol and methyl iodide.
