Sentence A contains an action verb. The word "ran" comes from the verb "to run," which is an action verb.
None of the other sentences contain an action verb. An easy way to see if there is an action verb in a sentence is to look if the subject of the sentence is doing something. In option B, Sarah is not doing anything, she simply only feels tired. Options C and D also are incorrect because the subjects of the sentences are not doing any actions.
