Final answer:
The freezing point of barium chloride is not provided among the given options.
Step-by-step explanation:
The freezing point of barium chloride can be determined by considering the properties of the Celsius scale. On the Celsius scale, the freezing point of water is 0°C. Therefore, since barium chloride is not water, its freezing point will be different. It is important to note that the boiling point of water is 100°C on the Celsius scale, which is unrelated to the freezing point of barium chloride. Therefore, the correct answer to the given question is not provided among the options.
