The answer is A. A tertiary alkanol (3° alcohol) is one where the carbon bearing the –OH group is attached to 3 other carbon atoms.

A. 2-methylpentan-2-ol
OH is on carbon 2
That carbon is attached to:
a methyl group (CH₃)
carbon chain on left
carbon chain on right
3 carbon attachments → TERTIARY alcohol
B. 2-methylpentan-1-ol
OH is on carbon 1 (end carbon) primary alcohol
C. pentan-3-ol
OH on carbon 3
attached to only 2 carbons secondary alcohol
D. pentan-2-ol
OH on carbon 2
