What is the difference between direct and indirect characterization

Direct characterization is when the narrator tells the reader something about a character. Indirect characterization is when the narrator shows the reader something about the character through the character's actions, things the character says, or things other characters say.

Explanation:

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.
