Answer:
C. The temperature increase went down because it became cooler as the sun went down for the night
Step-by-step explanation:
It is natural to have high temperatures when the sun is up, and as dusk begin to set, the temperature of a place drops. L
Going by the above stated fact, to explain the hours after the peak increase in temperature, it is plausible to conclude that as the sun went down, it became cooler for the night. That's why we have the lowest temperature displayed on the graph between 10 PM to 11:59 PM.
