If an event happens every calendar year, it is described as:

• A. Yearly (annually)
• B. Biweekly
• C. Daily
• D. Triennial

Answer: (A)

Expressing how often something happens is about frequency. If an event happens every calendar year, you describe it as yearly or annually. Yearly means it recurs once per year, regardless of whether that year has 365 or 366 days. Annually is a synonym with the same meaning. This differs from daily (every day), biweekly (typically every two weeks), and triennial (every three years). So for something that happens once each year, yearly is the best fit.
