  • A1900
  • B2100
  • C2200
  • D2400

Step-by-Step Solution

A year that ends in 00 is a leap year only when it is divisible by 400. Dividing by 400: 1900, 2100 and 2200 leave a remainder, so they are ordinary years of 365 days. But 2400 ÷ 400 = 6 exactly, so 2400 is a leap year.
Answer: D) 2400
