Phenol is more acidic than cresolCresol has an electron donating methyl group, which reduces its electron deficiency of the phenol group and hence acidity. The methyl group has +I effect as well as hyperconjugation effect, both of which increase the electron density in the O-H bond, and hence all cresols are weaker acids.
 
 
Hence option B is correct
