Select odd one out which does not fit as required and justify your answer
Si, S, P, C `" "` Electrical conductivity

Explanation

To solve the question of identifying the odd one out based on electrical conductivity from the elements Si (Silicon), S (Sulfur), P (Phosphorus), and C (Carbon), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Electrical Conductivity of Each Element:**
- **Silicon (Si):** Silicon is a semiconductor. It has some conductivity but is generally not considered a good conductor of electricity in its pure form.
- **Sulfur (S):** Sulfur is a non-metal and is generally a poor conductor of electricity.
- **Phosphorus (P):** Phosphorus is also a non-metal and does not conduct electricity well.
