Answer:
d. FRUGALITY.
Step-by-step explanation:
Benjamin Franklin's popular almanac "Poor Richard's Almanack" was an almanac written by him under the pseudonym "Poor Richard". In it, he includes a number of proverbs and maxims about life and his extensive use of wordplay in the phrases he also made up.
The phrase "If you'd be wealthy, think of saving, more than of getting" reflects best the virtue of frugality. Franklin was famous for his simple life approach, proverbial advice mainly on industrial issues and frugality. To him, a man need not spend extravagantly but instead learn to save up and live a normal life.
