Answer:
The correct answer is - option B. The presence of pups is the independent variable, and the frequency of sentinel behavior is the dependent variable.
Explanation:
The independent variable in a study or experiment is a variable that is subject to change or manipulated to see the effect on the result of the study by influencing the dependent variable. In this study, the independent variable that is manipulated is the presence of the pups to see what is led to the behavior of meerkats.
