The correct answer is D. The teacher commanded the boys that they be quiet.
In this sentence, the teacher is using a direct command. The word “command” means to give an order or instruction that must be obeyed. The teacher is using the word “be” in the imperative mood, which is the mood used to give commands. The boys are the direct object of the verb “command.”
The other options are incorrect because they do not accurately reflect the meaning of the sentence. Option A is incorrect because the teacher is not saying that the boys should be quiet, she is commanding them to be quiet. Option B is incorrect because the teacher is not calling the boys, she is commanding them. Option C is incorrect because the teacher is not urging the boys, she is commanding them.
Here are some additional examples of direct commands:
- Sit down.
- Stop talking.
- Go to your room.
- Do your homework.
