Which one of these statements would be considered inappropriate in formal writing?

AHe reviews the reports of his assistants.
BHe hates to be late.
CNext, he prepares to conduct his experiments.
DDr. Thomson arrives promptly each morning.

Verified Answer :

"He hates to be late" - it should be "he prefers not to be late" or something similar in formal writing.

I believe that B. would be inappropriate in formal writing because its just kind of rude to say. I would re-word it as: "He dislikes being late" or something like that because "hate" is just a cruel and informal word to use.
Hope this helps!!! (:
