Which of the following is meaningless ?

Options

A. XLVI
B. IC
C. LXXIX
D. DLXIX

Answer

To determine which of the options is meaningless, we will analyze each Roman numeral provided in the question.

### Step-by-Step Solution:

1. **Analyze Option A: XLVI**
- XL = 50 - 10 = 40
- VI = 6
- Therefore, XLVI = 40 + 6 = 46.
- This option is valid.

2. **Analyze Option B: IC**
- In Roman numerals, 'I' can only be placed before 'V' (5) and 'X' (10) to indicate subtraction.
- 'I' cannot be placed before 'C' (100) as it does not follow the rules of Roman numeral formation.
- Therefore, IC is meaningless.

3. **Analyze Option C: LXIX**
- LX = 50 + 10 = 60
- IX = 1 (10 - 1)
- Therefore, LXIX = 60 + 9 = 69.
- This option is valid.

4. **Analyze Option D: DLXIX**
- D = 500
- LX = 50
- IX = 9
- Therefore, DLXIX = 500 + 50 + 9 = 559.
- This option is valid.

### Conclusion:
The only option that is meaningless is **Option B: IC**.
