Text Solution

Verified by Experts

The correct Answer is:
B
`-M` and `-I` will increase acidity `-M` is effective at ortho and para positions onlyl while `-I` effect will operate will at all position but it is distance dependent.
`+M` and `+I` will dercease acidity but `+M` will be effective at ortho and para only.
H-bonding in phenol derivative is also consider for the comparison of acidity.
