Answer:
A. Whether or not a receiver is named in a sentence.
Step-by-step explanation:
A transitive verb or action is one where the action is received by a direct or indirect object. That means the sentence must have a direct or indirect object for the verb to be called a transitive verb.
On the other hand, an intransitive verb/ action is where there is no specified object to receive the action.
Therefore, the main difference between a transitive and an intransitive action verb is whether or not there is a receiver present or named in the sentence.
Thus, the correct answer is option A.
