natural selection is
the same thing as evolution.
the outcome of differences in survival and reproduction among individuals that differ in details of heritable traits.
the survival of strongest.
a random event in nature.

Explanation:

• Option 1: Natural selection is a mechanism of evolution, not the same as evolution itself. So this is incorrect.
• Option 2: Natural selection occurs when individuals with heritable traits that enhance survival and reproduction leave more offspring, leading to changes in trait frequencies. This matches the definition.
• Option 3: "Survival of the fittest" (often misinterpreted as "survival of the strongest") is a misnomer. Fitness relates to reproductive success, not just physical strength. So this is incorrect.
• Option 4: Natural selection is not random; it acts on heritable traits that affect survival and reproduction, so it is a non - random process. This is incorrect.

Answer:

B. the outcome of differences in survival and reproduction among individuals that differ in details of heritable traits.
