Which of the following is a leap year?

Options

A. 1800
B. 1900
C. 1700
D. 2000

Answer

To determine which of the following years is a leap year, we can follow these steps:

### Step 1: Understand the rules for leap years
A year is a leap year if:
- It is divisible by 4.
- However, if the year is a century (ending with 00), it must also be divisible by 400 to be considered a leap year.

### Step 2: Analyze the given years
Let's assume we have the following years to check: 1800, 1900, 1700, and 2000.

### Step 3: Check each year for leap year status
1. **Check 1800:**
- 1800 is a century year.
- Check if it is divisible by 400:
- 1800 ÷ 400 = 4.5 (not divisible)
- Conclusion: **Not a leap year.**

2. **Check 1900:**
- 1900 is also a century year.
- Check if it is divisible by 400:
- 1900 ÷ 400 = 4.75 (not divisible)
- Conclusion: **Not a leap year.**

3. **Check 1700:**
- 1700 is a century year.
- Check if it is divisible by 400:
- 1700 ÷ 400 = 4.25 (not divisible)
- Conclusion: **Not a leap year.**

4. **Check 2000:**
- 2000 is a century year.
- Check if it is divisible by 400:
- 2000 ÷ 400 = 5 (divisible)
- Conclusion: **It is a leap year.**

### Final Conclusion
Among the years checked, **2000 is the only leap year.**
