Choose the pair in which the words are differently related from the rest.

The correct answer is C. Extravagant: Thrifty.

In the other three pairs, the words are antonyms. Honest is the opposite of cheat, good is the opposite of nice, and seldom is the opposite of often. However, extravagant and thrifty are not antonyms. They are both words that describe how someone spends money. Extravagant means spending a lot of money, while thrifty means spending money carefully.

Here are some examples of how the words in the other three pairs can be used in a sentence:

• The man was honest, even when it was difficult.
• The woman was good to her friends and family.
• The couple seldom saw each other, but they were still in love.

Here is an example of how the words in the fourth pair can be used in a sentence:

• The woman was extravagant, and she often spent more money than she had.
• The man was thrifty, and he always tried to save money.
