Which of the following pairs of compounds may be regarded both as functional isomer and position isomer?

Functional isomers Position isomers They are called positional isomers.

o -cresol and p -cresol:they are position isomers but not functional isomers Benzyl alcohol and o-cresol:

They are both fuctional and position isomerism shows

They are functional isomerism shows but not position isomerism

Benzyl alcohol:

[a] Benzyl alcohol [b]Methoxy benzene

They show functional isomerism but not positional isomerism

Final answer is option A
