The graph below depicts the frequency of expression of the range of leg lengths in a population of crickets:

In this species, leg length is directly related to jump height: The longer the legs, the higher the cricket can jump. The crickets are being preyed on by a newly introduced species of rodent, and the best way to evade the predator is to jump out of reach. Which of the following graphs represents the range of leg length most likely to result from this selection pressure over a long period of time?

The peak of the bell curve has shifted to the left, with a greater frequency of short leg length and a lower frequency of crickets with longer legs.
The peak of the bell curve has shifted to the right, with a greater frequency of crickets with long legs and a lower frequency of crickets with short legs.
The peak of the bell curve is still in the center, but at a much higher value with steeper decline on either edge. This means there was an increase in crickets with average leg length and fewer crickets at either extreme of leg length.
There are now two peaks on the bell curve, with a dip, or decrease, at the center, representing a lower frequency of crickets with average leg length and increased frequencies of both long and short legs.

The peak of the bell curve has shifted to the right, with a greater frequency of crickets with long legs and a lower frequency of crickets with short legs.

The given condition would lead the directional selection of the crickets with long legs. Directional selection leads to shifting of curve in one direction, which is more suitable.

The crickets with short leg get easily caught by predators, so, after sometime, there would be a decrease in number of the crickets with short leg. At the same time, the crickets with long leg would manage to save themselves and their number would comparatively increased.
