Answer: The verb in the sentence provided is transitive.
Explanation: A transitive verb is a verb that needs to modify an object in order to make sense and express a complete thought. Therefore, transitive verbs cannot function without an object. The main verb in the sentence provided is "read". "Read" can be used either as a transitive or an intransitive verb; however, in this sentence, "read" has been used as a transitive verb since it is followed by a direct object ("her book"), which is receiving the action of "read".
