Which sentence is an example of a pun? Rome was not built in one day, and Greece was built in three. Raul kept reminding Justin that he should not judge a book by its cover. The cow stood in udder amazement when she was unable to produce milk. Never bite the hand that feeds you.

D

Explanation:

D is a pun because "udder"refers to a cows udder rather than the word "utter" (complete; absolute)

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.
