There are several ways selection can affect population variation:
stabilizing selection
directional selection
diversifying selection
frequency-dependent selection
sexual selection
As natural selection influences the allele frequencies in a population, individuals can either become more or less genetically similar and the phenotypes displayed can become more similar or more disparate. In the end, natural selection cannot produce perfect organisms from scratch, it can only generate populations that are better adapted to survive and successfully reproduce in their environments through the aforementioned selections.

Answer is C Anaguzman is right i was wrong so i put up this so as not to confuse anyone.
Answer:
Abiotic factors include water, sunlight, oxygen, soil and temperature.
Explanation:
looked up on google ;)
If it hits a single atom, a "product" can be broken. But only until it is a single molecule will a "molecule" be separated. Of starters, oxygen, H2O, always appears like oxygen in millions. But if you split it into smaller and lesser parts, say half, you can divide it only until you get 2 hydrogen and 1 oxygen. It's no longer water if you divide it further. It's going to be another matter.
