Because we can reproduce with just one and if more eggs were released, the female reproductive life (which is 40 years) would be shorter and so there would be less time for every female human to reproduce since the amount of eggs is limited. (Also fraternal twins come from 2 eggs released at the same time)
I'm not quite sure what happens to Fay so I didn't finish but hope it helps
Answer:
I am 98% sure that the answers are B and A
Explanation:
Electric field due to a point charge is given by formula

now due to negative charge also the magnitude of electric field will be same
only difference is the direction of field due to negative charge is radially inwards
now we can say that net field due to these two charges is given as



now it is given that distance r is very large than "d" so we can say

<em>so above is the electric field due to dipole</em>
