generally the more carbons in the acid, the weaker it gets.
Alcohold are much weaker acids than carboxcilic acids.
A ) phenol, C6H5OH, is an exception, it should be stronger than CH3OH
B) Wrong, see my first statement.
C)This one is right, see A)
D) Wrong, see my second statement.

look at pKa's the lower the number the stronger the acid. here's your one example:
phenol pKa is 10 MeOH has a pKa of 16. Phenol is the stronger acid
