Which of the following is not meaningful ?

Options

A. CI
B. CII
C. IC
D. XC

Answer

To determine which of the given options is not a meaningful Roman numeral, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Identify the Roman Numerals:**
- The options given are:
- Option 1: CI
- Option 2: CII
- Option 3: IC
- Option 4: HC

2. **Convert Each Option to Its Decimal Value:**
- **Option 1: CI**
- C = 100
- I = 1
- Therefore, CI = 100 + 1 = 101 (Meaningful)

- **Option 2: CII**
- C = 100
- I = 1 (appears twice)
- Therefore, CII = 100 + 1 + 1 = 102 (Meaningful)

- **Option 3: IC**
- I = 1
- C = 100
- In Roman numerals, I can only be subtracted from V (5) and X (10), not from C (100). Therefore, IC is not a valid Roman numeral (Not Meaningful).

- **Option 4: HC**
- H is not a valid Roman numeral. Roman numerals only include I, V, X, L, C, D, and M. Therefore, HC is not meaningful (Not Meaningful).

3. **Conclusion:**
- From the analysis, both Option 3 (IC) and Option 4 (HC) are not meaningful. However, since the question asks for one option that is not meaningful, we can conclude that **Option 3: IC** is the most commonly recognized invalid Roman numeral.

### Final Answer:
The option that is not meaningful is **Option 3: IC**.
