Correct option (c)

For correct Option C

Individuals who are better prepared to compete for scarce resources are more likely to live and procreate in an environment with low mortality rates and strong resource competition. This would favor a K-selected life history strategy, which is characterized by a long lifespan, a low birth rate with significant investment in each child, and a sluggish pace of development.

K-selection is a technique that increases the likelihood of offspring surviving for a very long time in a stable environment with few resources. In such a setting, slower rates of reproduction are more advantageous, with parents devoting more resources to each child. This increases the likelihood that kids will live to adulthood and procreate in the future.

For Incorrect Option B

Iteroparity, or multiple reproductive events over the course of an individual's lifetime, is more likely to occur in more stable environments, while semelparity, or the production of many offspring in a single reproductive event, is more likely to occur in environments with high mortality rates. 

For Incorrect Option D

R-selection is a life history strategy that is more prevalent in habitats with abundant resources and high mortality rates. It is characterized by a high reproductive rate and little investment in each child.

For Incorrect Option A

A life history strategy known as semelparity involves an organism producing all of its children in a single reproductive event before passing away. This tactic is frequently seen in situations with high rates of mortality and few resources, where there is a substantial chance of passing away before the next opportunity for reproduction.
