Here's why:
* Transitive verb: A verb that requires a direct object. The direct object is the thing or person that receives the action of the verb.
Let's break down the other options:
* B. A takes no objects or complements: This describes an intransitive verb.
* C. A verbal phrase in which is an infinitive: This describes an infinitive phrase, not a transitive verb.
Example:
* "The dog chased the ball."
* "Chased" is the transitive verb.
* "Ball" is the direct object, receiving the action of chasing.
