Answer:
A). The clouds that cover the mood dissipate quickly.
Step-by-step explanation:
The sentence which carries a subject and verb that agree is option A as it correctly employs the verb(plural) with the subject(plural) i.e. 'the clouds'. One of the most significant grammatical rules includes the subject-verb agreement where the verb must agree to the subject of the sentence in order to unify the sentence and ensure the smooth flow of ideas without any errors that may break the continuity. It makes the sentence easier for the readers to understand and convey the meaning effectively. Thus, the correct answer is option A as it correctly employs the subject-verb agreement.
