A population that is not undergoing natural selection displays what type of distribution?

A population that is not undergoing natural selection displays what type of distribution? - Normal - Disruptive - Directional - Stabilizing * I am thinking it is the correct answer would be the second choice, but I am not very sure. Any help would be greatly appreciated!

1. All organisms are undergoing natural selection all of the time. Therefore, the premise of the question is invalid.
2. A population that is not undergoing natural selection is either composed of genetically identical individuals, is a population of one, or is extinct.
3. I think the answer is the normal distribution. Not all organisms are undergoing natural selection at all times. I disagree with that. For instance a population that is expanding into a region that has favorable environmental conditions and is not densely populated will not be exposed to selection pressure. This population will be controlled by stochastic factors.
