The correct answer is A. Mutations that increase reproduction
Explanation:
Evolution is a natural process in life that occurs when genes and traits in a population change over time or generations. One of the main processes that cause this, is the natural selection that occurs when in a population of same organisms some traits caused by mutations represent an advantage to survive or reproduce because they make organisms more likely to survive or increase reproduce and this makes these traits be naturally selected or prevail over time. In this way, the natural selection of mutations or traits introduces new genes in a population. According to this, evolution occurs when nature selects mutations that increase reproduction.
