Answer:
(i) Individuals most adapted to their environments have a better chance of surviving to reproduce.
(ii) Individuals compete for resources.
(iii) The traits within a population vary and are heritable.
Explanation:
Adaptation was an important aspect of Darwin's theory, so the first statement must be true. The traits within a population vary which leads to natural selection, so the second-last statement is also true. Resources are limited and therefore, competition is abundant, and this, the 3rd option is also true.
