To determine which compound is a tertiary alkanol, we need to identify the carbon atom bonded to the hydroxyl (-OH) group and count how many other carbon atoms it is directly bonded to.

To determine which compound is a tertiary alkanol, we need to identify the carbon atom bonded to the hydroxyl (-OH) group and count how many other carbon atoms it is directly bonded to.

• A primary alkanol has the -OH group attached to a carbon atom that is bonded to only one other carbon atom (R-$\text{CH}_2$-OH).
• A secondary alkanol has the -OH group attached to a carbon atom that is bonded to two other carbon atoms ($\text{R}_2$-$\text{CH}$-OH).
• A tertiary alkanol has the -OH group attached to a carbon atom that is bonded to three other carbon atoms ($\text{R}_3$-$\text{C}$-OH).

Let's analyze each option:
