​Which sentence correctly uses a hyphen in a compound Modifier?

A. My little sister was well-behaved throughout the entire ride.

B. The supplies that you brought were much-needed.

C. Enrique’s dream is to become a full-time singer.

D. A newly-married couple moved into the apartment across the hall.

Answer:- C. Enrique’s dream is to become a full-time singer.

The option C implements the hyphen correctly. In the added choices, the words there do not require hyphens. In option A, two adjectives can be hyphenated but not after a noun. In simpler words, the expression “well-behaved little sister” is right unlike “my little sister was well-behaved” that is not allowed in the rules of the English language.
