Because I do not know the context of what is "cool," I am going to assume that is referring to the weather/temperature.
In Spanish, we use the verb "hacer" in expressions that refer to weather conditions.
The direct translation of "It is cool," is:
Hace fresco.
We use the third singular form of the verb hacer because we are talking about the weather.

The best answer for this is D. Comes :)
Translation:
At 1 in the afternoon you eat the vegetables.
Tomes means to drink, while Comes means to eat.
