Final answer:
The question involves ecology concepts from biology, specifically about r-selected and K-selected species and their particular traits. The student's query is clarified by specifying that if K is selected, then M must also be selected when comparing these ecological strategies.
Step-by-step explanation:
The question refers to r-selected and K-selected species, which is a concept from ecology in biology. When comparing r-selected and K-selected species, an accurate comparison would consider the reproductive strategies and population dynamics that characterize these different types of species. The correct answer to the question If she selects K, she must select M, using the provided reference, would be B) If K is selected, then M must also be selected. However, to provide a proper comparison of r-selected and K-selected species, we need to look at their specific traits, such as reproductive rate, survival strategy, and type of habitat.
