The answer is D (maxim).
Benjamin Franklin's witty quotes are maxims.
Maxims are short and easy to remember sentences that compress general truths or thoughts that, in some way, help to set up moral parameters. Maxims usually become famous for having been said by founder fathers, scientists, politicians, or prominent members of literature.
One of the most famous maxims of Franklin is "early to bed, early to rise, makes a man healthy, wealthy, and wise."
