Answer:
When an individual develops the traits
needed to survive and reproduce
Step-by-step explanation:
the second option is wrong because evolution isn't an immediate change but takes thousands to millions of years depending on what is evolving.
The third option is close but the difference is natural selection is when weaker animals of a species die out while the stronger ones survive for example, when one bird hatches before the other the hatched bird may push the egg out of the nest to get more food. That is an example of natural selection. It is a part of evolution but not evolution itself.
