D. You define if a quadratic equation has an answer or not by the delta (the calculation inside the sqrt on the quadratic formula). So you simply calculate b^2 -4ac, if the answer is equal or greater than zero there is a solution, if not there isn’t. (Consider ax^2+bx+c) Hope it helped :)

All 4 stages span a total of 4 weeks or 28 days.

Egg - 2 days
Larva - 7 days
Pupa - 5 days
Adult - 14 days

This means that the larva exists for 7/28 = 25% of the time.

So, 25% of the randomly selected developing bees would be larva.

25% of 200 is 50. So, the answer is A.

Edit: The question is ambiguous. If by developing bees they exclude all the adult bees, then larva exist for 50% of the time and the answer would be 100.
