(D) She gave me the Lincoln Laser billing records before she left on vacation.

Explanation:

The subject verb agreement in options C and D are correct.

Option C: The use of 'has known' is in the past form, thus the sentence is correct.

Option D: 'gave' is also a past tense, which agrees with the sentence as she had left for the holiday.

Whereas, Options A and B are wrong.

Option A: the board has chosen, meaning 'past tense' thus the use of 'accepts' which is a present tense is wrong.

Option B: the new policy had been started since yesterday, so the verb 'begun' which is the "third form of the verb' is wrong and should be used alongside a helping verb thus making it 'had begun'.
