Any species growing ...$A$... under unlimited resource conditions can reach enormous population densities in a short time. Darwin showed how even $\ldots$ $B$... growing animal like elephant could reach enormous numbers in absence of check and that characteristics of organism is called $C$

Choose the correct option for $A , B$ or $C$ respectively

Maximum growth rate occurs in:

The formula for exponential population growthis

Population growth of a country depends upon

$I.$ Population evolve to maximise their reproductive fitness, also called Darwinian reproductive fitness (higher $r$ value), in the habitat in which they live

$II.$ The population growth rate $r$ is inversely related to generation time

$III.$ The housefly, which has a short life span and produces a large number of eggs, could be considered as a ' $K$ ' selected species

$IV.$ Under a particular set of selection pressures, organisms evolve towards the most efficient reproductive strategies

$V.$ Life history traits of organisms have evolved in relation to the constraints imposed by biotic and abiotic factors in their habitat Select the combination of correct statements
