Common lit you have the right to remain silent

i don't see any questions on your profile, currently, but i'd be happy to try and with any problems that you have, so long as i understand the problem myself.

c. barbarians with unexpected intelligence  

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.
