Answer: vvv

Step-by-step explanation:

Aldehydes and ketones react with alcohols to form hemiacetals/hemiketals by adding an alcohol molecule to the carbonyl group of the aldehyde or ketone. This reaction is catalyzed by acid or base.

To form acetals/ketals, a second alcohol molecule is added to the hemiacetal/hemiketal under acidic conditions, which forms an acetal or ketal. The reaction involves the elimination of a water molecule, and is also catalyzed by acid.
