Detailed explanation-1: -So, the correct answer is ‘High competitive ability’.
Detailed explanation-2: -R-selected species are those that produce a large number of offspring and contribute few resources to each individual offspring. They often offer little to no parental care, have high offspring mortality, short life spans, and small body sizes.
Detailed explanation-3: -Among the traits that are thought to characterize r-selection are high fecundity, small body size, early maturity onset, short generation time, and the ability to disperse offspring widely. Organisms whose life history is subject to r-selection are often referred to as r-strategists or r-selected.
Detailed explanation-4: -Although not always the case, r-selection is more common among smaller animals with shorter lifespans and, frequently, non-overlapping generations, such as fish or insects. The young tend to be precocial (rapidly maturing) and develop early independence.
