From the words or group of words lettered A to D, choose the word or group of words that best completes the sentence below. The order is that everyone must be ....... bed by midnight.
A. on B. inside C. in D. within
Correct Answer: C
Explanation
“In bed” means that you are not just on your bed but also very much ready to sleep. It implies that you are under under the sheets. "On the bed" means "on the surface" of the bed. The person or object is not under any covering. With "on," there is always an article, or a possessive, or other determiner. "On" never appears alone with "bed."
