A sample of water begins to freeze at —3°C at normal temperature and pressure. What can you say about its boiling point?

Correct option is B

The boiling point of water at normal temperature and pressure is 100⁰C. This means that, under normal conditions, water changes from a liquid state to a gaseous state at 100⁰C.
However, the information provides states that the water begins to freeze at -3⁰C. This implies that the temperature of the water is below the freezing point of 0⁰C. When the temperature of the water is below its freezing point, it transitions from a liquid state to a solid state. This indicates that the water is in a solid state at temperatures below -3⁰ C. Since the water is in a solid at -3⁰C, it is not at the boiling point, and therefore it will not boil at this temperature.
