The correct option is A.
Fitness refers to the quantitative representation of natural and sexual selection within an evolution. Fitness can be defined in respect to a genotype or a phenotype. Relative fitness is described as the survival or reproductive rate of a genotype or phenotype relative to maximum survival or reproductive rate of other genotypes in the population. Thus, the fitness of a population can be determined by finding out the number of offspring that survive to adulthood.
Reducing the activation energy can increase the rate of a reaction. Reducing the activation energy would mean that less energy is required to process a reaction, whereas increasing activation energy would require more energy to process a reaction.
