Explanation:

Verbal tenses indicate when the action, state or phenomenon expressed by the verb occurs. When a change of verbal tense occurs within the sentence, it is necessary that this change does not interrupt the relation of coherence and cohesion of the text, because this will leave the phrases meaningless and will not allow the understanding of the reader. For this reason, the letters B, C and D are those that present an acceptable change in verbal tense, because the change maintains the coherence and cohesion of the sentence.
