Final answer:
The sentence 'The animals protect their young' is transitive because the verb 'protect' acts on the direct object 'their young,' fulfilling the requirement for a transitive verb. option A is the correct answer.
Step-by-step explanation:
The sentence 'The animals protect their young' features a direct object, which is 'their young.' Since the verb 'protect' is acting on this direct object, the sentence is classified as a transitive verb.
Verbs that do not have a direct object are known as intransitive verbs. In this case, because the verb 'protect' sufficiently operates on an object, it is indeed transitive, and so, the correct answer to the question is option (a) Transitive.
In this sentence, 'animals' is the subject and 'their young' is the object of the action 'protect'.
