Miscible liquids are separated by a. Distillation.

Here's a step-by-step explanation:

1. Miscible liquids are liquids that can mix together in all proportions without separating into two layers. An example of miscible liquids is alcohol and water.

2. To separate miscible liquids, we use a process called distillation.

3. In distillation, the mixture is heated to a temperature where one of the liquids will start to evaporate. This is usually the liquid with the lower boiling point.

4. The vapor of the evaporated liquid is then collected and cooled down in a separate container. This process is called condensation.

5. The liquid that remains in the original container is the other component of the mixture.

6. This process can be repeated if necessary to increase the purity of the separated liquids.

So, the correct answer is a. Distillation.
