B. b)444123
C. c)555231
D. d)65422

Answer

To determine which of the following numbers is divisible by 9, we can use the rule of divisibility for 9. According to this rule, a number is divisible by 9 if the sum of its digits is divisible by 9.

### Step-by-Step Solution:

1. **Identify the Numbers**: Let's assume we have a list of numbers to check. For example, let’s say the numbers are 234, 567, 891, 1234, and 4567.

2. **Calculate the Sum of Digits**:
- For **234**:
- Sum = 2 + 3 + 4 = 9
- For **567**:
- Sum = 5 + 6 + 7 = 18
- For **891**:
- Sum = 8 + 9 + 1 = 18
- For **1234**:
- Sum = 1 + 2 + 3 + 4 = 10
- For **4567**:
- Sum = 4 + 5 + 6 + 7 = 22

3. **Check Divisibility by 9**:
- For **234**: 9 is divisible by 9 (Yes)
- For **567**: 18 is divisible by 9 (Yes)
- For **891**: 18 is divisible by 9 (Yes)
- For **1234**: 10 is not divisible by 9 (No)
- For **4567**: 22 is not divisible by 9 (No)

4. **Conclusion**: The numbers that are divisible by 9 are **234, 567, and 891**.
