The correct option is D.

Enzymes are biological catalysts that speed up the rate of biochemical reactions in living systems by lowering the activation energy required for the reactions to occur. Enzymes take part in various reactions but they are never used up during the course of the reaction.  

Enzymes are very specific in action and will only catalyze certain reactions under optimal conditions. For a single examine to catalyze two different reactions, it implies that the enzyme either have two active sites or the molecules involve in the reaction are very similar in term of size and shape.

Both the freezing temperature and the melting temperature of water are the same O.C. Explain why a substance like water freezes
Galina-37 [17]
Because the melting/freezing point is the point at which the particles in a substance begin to go through the phase change
so for example at 0 degree's Celsius water starts to freeze, but at the same time also melts, its sorta like some of the particles are freezing while the others are melting at the same time, but if you go above 0 degrees then it melts, and if you go below it freezes
