C Correct answer
Explanation

Leap years occur less often than once every 4 years because century years (1700, 1800, 1900) are NOT leap years unless divisible by 400 (1600, 2000). This Gregorian calendar rule averages to 97 leap days in 400 years, not 100. The answer 'less than once in every 4 years' correctly captures this nuance.
