The least likely likely given the limits of fitness trade-offs is the eggs from the female laying 1000 eggs have larger yolks than the yolks of the eggs from the female laying 100 eggs.

Option: (C)

Explanation:

For the female fish breeding, the number of eggs laid may differ but it doesn't give the proper information if the female laying less eggs contains more yolk. Given that, the same fitness factor, the number of eggs laid does not mean level of concentration of yolk in the eggs.
