Solution
The correct option is D Reproductive success
Darwin fitness is more inclined to the reproductive fitness of an individual. Higher is the fitness of an individual, longer the individual will live to reproduce successfully. So, for the continuity of the race, the living beings have an innate ability to reproduce more offspring. Since the food resource is limited and there is an intense competition and struggle to ensure living by accumulating enough food and space. The everlasting competition among the organisms compel them to evolve according to the changing environment so as to utilise the natural resources well and survive successfully.
Darwin’s fitness is more concerned about reproductive success, he describes fitness as how successful an organism has been at passing on its genes. Organisms that are best adjusted to the environment are likely to be more successful in surviving and reproducing and that can only ensure their existence in the long run.
Other factors that help in selecting an individual by nature for evolution are good health, capacity to fight with others for availing the food resources from the resident population etc., but the fittest ones are the those that can reproduce successfully and pass on the genes to next generation.
