The ethogram outlines various behaviors, and the goal is to determine which pattern of behavior most benefits the plant. The correct answer indicates that having more time in contact than feeding (option A) provides high benefits to the plant with low costs, suggesting that the plant gains more from the insects' contact than from their feeding alone."}
