The correct option is A True
A compound adjective is formed when two or more words are joined together to form an adjective to modify the same noun. They are joined with a hyphen (-). Compound adjective can be formed by joining a noun and a past participle with a hyphen. E.g. Many vegetarians find meat-fed cats to be quite healthy. Here, meat is a noun and fed is a past participle of feed verb. Thus, option A is the correct answer.
