Three hydrocarbons A, B and C have melting points `-183^(@)C,-138^(@)C,and-95.3^(@)C` respectively. Which one has minimum number of carbon atoms in molecule?

Explanation

To determine which hydrocarbon (A, B, or C) has the minimum number of carbon atoms in its molecule based on their melting points, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Melting Points**:
- Hydrocarbon A: -183°C
- Hydrocarbon B: -138°C
- Hydrocarbon C: -95.3°C
