Solution

The least reactive towards nucleophilic addition reactions is benzophenone.

Explanation:

Ketones are less reactive than aldehydes. Both acetone and benzophenone are less reactive than acetaldehyde and benzaldehyde. But, benzophenone is least reactive due to the presence of two bulky aryl groups (i.e., steric hindrance).
