Question

Biannual is

• A. once in two years
• B. every year
• C. twice a year
• D. after every two years

Hint:

Bi means two, so think about how many times a year this happens.

Answer 1

The Correct Option is C

Step 1: Recall the meaning of the word.
Biannual is built from the prefix bi, meaning two, joined with annual, meaning yearly. So biannual describes something that happens two times within a single year.

Step 2: Check each option.
Option A, once in two years, actually describes the word biennial, a different term that is often confused with biannual. Option B, every year, describes annual, which happens only once a year, not twice. Option D, after every two years, again matches biennial, not biannual.

Step 3: Pick the matching option.
Option C, twice a year, is the correct sense of biannual, since the event occurs two times in one year.

Final Answer:
Biannual means occurring twice a year, so option C is correct. \[ \boxed{\text{C}} \]
