• B. Freezing point
• C. Boiling point
• D. Condensation Point

Answer 1

The correct option is B

Freezing point

The Explanation for correct option is:

Option B: Freezing point

1. The process in which a substance changes state from liquid to solid is called Freezing.
2. The temperature at which freezing happens is called freezing temperature.

The Explanation for incorrect options are:

Option A: Melting point

1. The process in which a substance changes state from solid to liquid is called Melting or Fusion.
2. The temperature at which this process occurs is called the melting point.

Option C: Boiling point

1. The process in which a substance changes state from liquid to gas is called vaporization.
2. The temperature at which this process occurs is called the boiling point.

Option D: Condensation point

1. The process in which a substance changes state from gas to liquid is condensation.
2. The temperature at which this process occurs is called the condensation point.

Hence, the correct option is Option B. Freezing point.
