Which of the following is tertiary benzylic alcohol?

Step-by-step solution

A benzylic alcohol has the -OH group attached to a carbon atom that is directly bonded to a benzene ring (benzylic carbon). For the alcohol to be tertiary ( 3^ ), the benzylic carbon must be bonded to three other carbon atoms (one from the benzene ring and two other alkyl groups). Let us analyze the given options: Option (326143): The structure is benzyl alcohol ( Ph-CH₂-OH ). The benzylic carbon is bonded to only one carbon atom (from the benzene ring). It is a primary ( 1^ ) benzylic alcohol. Option (326144): The
