The correct response is:

the mass of the mouse minus the mass of waste produced by the snake.

When a snake eats a mouse, its mass increases by the mass of the mouse, but it will also excrete waste, which means not all the mass of the mouse contributes to the increase in the snake's mass. Therefore, the increase in mass is the mass of the mouse minus the mass of waste produced.
