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 gains mass from the mouse, but it also produces waste as it digests the food. Therefore, the increase in the snake's mass would be the mass of the mouse minus any waste that is subsequently excreted.
