B) factor effect
C) level effect
D) main effect

Final Answer :
A
Explanation :
An interaction effect occurs when the effect of one independent variable on the dependent variable changes depending on the level of another independent variable. In this case, the effect of the type of weight loss program on weight loss differs between males and females, indicating an interaction effect. A factor effect would refer to the effect of a specific independent variable, while a level effect would refer to the effect of a specific level of an independent variable. A main effect occurs when the independent variable has a significant effect on the dependent variable regardless of any other variables.
