When a mixture of three miscible liquids is subjected to fractional distillation, liquid B is obtained in the receiver flask. The remaining mixture on further fractional distillation, A, is left behind in the distillation flask. On the basis of the results, comment on the critical temperatures of A, B and C when they are in gaseous state.

Explanation

To answer the question regarding the critical temperatures of liquids A, B, and C based on the results of fractional distillation, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Fractional Distillation**:
- Fractional distillation is a technique used to separate mixtures of liquids based on their boiling points. When a mixture of three miscible liquids is heated, the component with the lowest boiling point vaporizes first and can be collected.

2. **Identifying the Components**:
...
