Final answer:
The converse of the statement 'Water freezes below 0 degrees Celsius' is 'If water freezes, then it is below 0 degrees Celsius,' which corresponds to answer A.
Step-by-step explanation:
The converse of a statement reverses the direction of implication. The original statement is 'Water freezes below 0 degrees Celsius.' To write the converse of this statement, we swap the hypothesis and the conclusion. The converse statement is 'If water freezes, then it is below 0 degrees Celsius.' Therefore, the correct answer is A.
It is important to understand that the converses may not always be true even if the original statement is true. In the context of temperature and water states, the truth of the converse can depend on other conditions such as pressure or the presence of impurities, which can lower the freezing point of water.
