Why can organisms with useful traits be more successful in natural selection?
Answer and explanation
Correct answer: They can survive better and produce more offspring in the environment
Natural selection is governed by differential survival and reproduction, not simply by size. A useful trait gives an organism an advantage under particular environmental conditions, such as better camouflage, disease resistance, or efficient feeding. The organism may then survive longer and leave more offspring, increasing the trait’s frequency in the population. Option A is correct; B is an unjustified absolute, while C and D are biologically incorrect.
