This is a quadratic function. The y-axis labels mosquitoes (millions), and x-axis labels rainfall (centimeters). The vertex of the function is (2,4) and the function intersects with x-axis at (0,0) and (4,0). Which of these statements are true?
Choices:
A:The largest possible number of mosquitoes is 2 million mosquitoes.
B:The largest possible number of mosquitoes is 4 million mosquitoes.
C:More rainfall always relates to less mosquitoes.
D:More rainfall relates to less mosquitoes as long as rainfall is less than $2 \mathrm{~cm}$.
Please directly answer the question and provide the correct option letter, e.g., A, B, C, D.
