D.  all of the above, although I do find it hard to believe something like flour would have a melting point, I looked up my answer to double check.

Answer:

D all of the above

Step-by-step explanation:

Melting point represents the exact temperature at which the solid state changes to the liquid of a given substance. Water is one of the most commonly used elements to exemplify the melting point principle. For this solid state (ice) to take the form of liquid water, it must be exposed to a temperature of at least 0 °C. Thus, the melting point of water is equal to 0 °C.

The salt has a melting point of 801 ° C, the melting point of sugar is 185 ° C and the melting point of flour is 264 ° C. From this we can see that all these products have a higher melting point than water.
