Which term describes something that occurs once every year?

• A. Yearly (annually)
• B. Weekly
• C. Monthly
• D. Biennial

Answer: (A)

Frequency terms describe how often something happens, and in this case you’re looking for what means once per year. Yearly, also called annually, directly conveys that meaning—one event per calendar year. That matches the prompt’s requirement exactly. Other options refer to different intervals: weekly means every week, monthly means every month, and biennial means every two years. For example, a festival held yearly happens once each year, whereas a weekly meeting occurs every week or a biennial event happens every two years.
