Correct option is
D

Reproduction

  • In sexual reproduction, the offsprings, although similar to their parents, are not identical to them or to one another. This is because the recombination of genes in the zygote which develops a young one and thus receives some genes from the mother and some from the father. 
  • All the offsprings have genetic variations. In this way, sexual reproduction leads to a greater variety in the population. 
  • This means that a species (animal or plant) can adapt more quickly to changes in its surroundings (or environment). Hence, it can be said that reproduction leads to perpetuation or prolong the existence of race.

Therefore, the correct answer is option D.
