Answer: best adapted to the environment
Explanation: fitness can be thought of as fit for purpose. The most fit for purpose organism is the one best adapted to its environment.
Nevertheless, all the options are characteristic of adaptation
It is not particularly useful to discuss natural selection in terms of individuals and not populations. An advantageous mutation in one individual is the theoretical starting point for a better adapted population, but adaptation happens in a population very slowly if at all if it depends on a single individual. The smaller the population, the higher the probability that the adaptation will be eliminated by chance.
Exchange of gases in fish is very efficient because of: the large surface area of the gills. the large surface area of the blood capillaries in each gill filament. the short distance required for diffusion – the outer layer of the gill filaments and the capillary walls are just one cell thick.
