Solution

The correct option is C It is a stronger acid than water.
When a molecule of phenol loses a proton, it forms phenoxide ion which is stabilized by resonance as the negative charge is delocalized over the aromatic ring.
No such resonance is present when a water molecule loses a proton to form hydroxide ion.
Hence, phenol is more acidic than water.
