Is the answer either B or C? (I need some help)

Hi there, it's B. If you read closely, you can tell that it's written in a Persuasisve Form. The meaning of persuassive is: good at persuading someone to do or believe something through reasoning or the use of temptation.

(Hope this helps) Sky

i believe the answer is: b. mr. head had a long, tube-like face with a rounded open jaw and a short depressed nose.

this is because in the un-revised sentence it said that mr. heads face was long and tube-like, and he had a rounded open jaw. this is not a very grammatically correct because of how it seems to drag on with the and, replaced with, with, makes it sound more fluent in the description.
