Solution

The correct option is D
More green beetles survive than the red

The green beetles cannot be seen by birds. So they are not eaten. Increased feeding of red beetles by birds will result in drastic reduction of red beetles and increased number of green beetles in the population.

Some green beetles appear among the red beetle because:

Red-coloured beetles are living on green leaves of bushes. These beetles increase in numbers by sexual reproduction. Crows, being their predators, consume beetles and regulate their population. During reproduction, few beetles develop green colour instead of red colour. This variation in body colour gives green coloured beetles an advantage and over the years, the number of green beetles in the population will increase generation after generation.
