 A 0 F B 32 C C 50 C D 0 C
Explanation:

Detailed explanation-1: -We’ve all been taught that water freezes at 32 degrees Fahrenheit, 0 degrees Celsius, 273.15 Kelvin.

Detailed explanation-2: -The freezing point of water is zero degrees Centigrade or 32 degrees Fahrenheit. Rather, we can say that zero degrees are the point at which water is melting at the same rate it is freezing. Hence, creating a balance.

Detailed explanation-3: -Fresh water freezes at 32 degrees Fahrenheit but seawater freezes at about 28.4 degrees Fahrenheit, because of the salt in it.

Detailed explanation-4: -Answer and Explanation: 0 degrees on the Celsius temperature scale is equal to the freezing point of water. In Fahrenheit, the freezing point of water would be equal to 32 degrees Fahrenheit. On the Kelvin scale, the freezing point of water would be equal to 273.15 degrees K.
