Which option is the correct abbreviation for an ounce?

• A. oz.
• B. ounce
• C. ozs
• D. oz

Answer: (D)

Understanding how ounces are abbreviated helps you read and write recipes and labels quickly and consistently. The common abbreviation for an ounce is oz, and in most culinary contexts this two-letter form is written without a trailing period. That makes it concise and easy to scan on ingredient lists, which is why oz without punctuation is the best choice here. The version with a period, oz., is used in some style guides or older texts, but it’s less common in modern recipes and packaging. Spelling out the word “ounce” isn’t an abbreviation at all, so it isn’t the right pick when the question asks for the shortened form. Also, plural forms don’t typically add an s to the abbreviation—2 oz is standard, not 2 ozs.
