Answer:
C. "Walked the world over to get her a blade o' grass" helps the reader understand how devoted Mr. Craven was.
Step-by-step explanation:
Figurative language refers to words and phrases that are metaphorical and diverge from their literal meaning. Thus, the phrase "Walked the world over to get her a blade o' grass" is not used in a real or literal circumstance; Mr Craven did not actually walk over the world to bring his wife some grass. In fact, it means that Mr Craven was crazy about his wife and would have done whatever she wanted to make her happy.
