Certified Clinical Medical Assistant Exam Practice Question

Correct Answer: C

Rationale: A calendar year typically consists of 365 days, which accounts for the Earth's complete orbit around the Sun. This standard is used in the Gregorian calendar, the most widely adopted calendar system.

Option A (300 days) is incorrect as it undercounts the annual cycle significantly. Option B (350 days) also fails to represent the full duration of a year. Option D (400 days) exceeds the actual number of days in a year, leading to an inaccurate representation. Thus, 365 days is the established norm for a calendar year, reflecting the Earth's orbital period accurately.
