The correct answer is D. libertine.
A libertine is a person who is unrestrained by the rules of morality or tradition. They are often seen as being immoral or promiscuous. The word libertine comes from the Latin word libertinus, which means "freedman." In ancient Rome, a libertinus was a slave who had been freed by his master. Libertines were often seen as being outside of the social order and were often looked down upon.
In modern times, the word libertine is still used to describe someone who is unrestrained by the rules of morality or tradition. However, the word is not always used in a negative way. Some people may see libertines as being free-spirited and independent. Others may see them as being immoral or promiscuous.
The other options are incorrect. A freelance is someone who works independently, without being employed by a company or organization. A criminal is someone who has committed a crime. A loafer is someone who is lazy and does not want to work.
