Answer:
A. 35 °C
Step-by-step explanation:
You want to know which of the temperatures 5, 10, 15, or 35 °C is most favorable to mosquito breeding.
Breeding
Mosquitos are nonfunctional below 50 °F (10 °C), and are lethargic at 60 °F (15.6 °C). They prefer 29 °C, and their breeding falls off at higher and lower temperatures.
Of the temperature choices offered, mosquitos would breed fastest at 35 °C.
