The correct response is: the mass of the mouse minus the mass of waste produced by the snake.

When a snake eats a mouse, it absorbs nutrients from the mouse for growth and energy. The increase in the snake's mass will be the mass of the consumed mouse, minus any waste that the snake excretes. The original mass of the snake and the waste produced do not contribute to the increase in mass from the digestion of the mouse.
