Which sentence correctly uses a hyphen in a compound modifier?

A hyphen is used in a compound modifier placed before the noun it describes: “full-time” modifies “singer.” In A and D, the modifiers come after linking verbs (“was” and “were”), so they are not hyphenated in this use. C is written “newly married” because an adverb ending in “-ly” is not joined to the following adjective with a hyphen.
