The correct answer is C. Apparel.
Apparel is a noun that refers to clothing or other items worn on the body. It is derived from the Old French word apareillier, which means "to prepare" or "to equip." The word apparel first appeared in English in the 14th century.
The word apparel is often used interchangeably with the word clothing, but there is a subtle difference between the two words. Clothing refers to any article of dress, while apparel typically refers to outerwear or formal clothing. For example, you might say that you are going to buy some new clothes, but you would not say that you are going to buy some new apparel.
The word apparel can also be used figuratively to refer to anything that covers or protects something else. For example, you might say that a tree's leaves are its apparel.
The word apparel is spelled with two "p"s and one "r." The other options, A, B, and D, are all incorrect spellings.
