The correct answer is extinction-adaptive characteristics of a species are not adequate. Extinction is an evolutionary term referring to the termination of a species because they are no longer able to survive under the conditions of their environment.
Natural selection is wrongly explained here since it is the evolutionary mechanism according to which the fittest organisms survive.
Gene recombination is also wrongly explained. It is the exchange of genetic material between different chromosomes or different parts of the same chromosome.
Mutation is also wrongly explained since it is a permanent change in the nucleotide sequence of the genome.
