You should always feed a horse with a flat palm so they don't bite you.
There is not enough to answer this question
The answer would be B. Answers A, C, and D are fragments of a sentence, lacking a complete idea.
Ex:
A) "because I had not slept for hours" - "because" what? An example of a complete version of this sentence would be "My head hurts because I had not slept for hours."
Answer:
Family (correct me if im wrong)
The sentence with the correct subject-verb agreement is D. The staff get pizza and then eat together in the break room.
In this case the word staff is considered a plural because ever individual element is doing the same activity in the same place "together" but they are not actually performing the activity as an unit. They are side by side eating.
The other options are not correct because they don't follow teh subject verb agreement.
