The electrically operated drain gun is an adaptation of the?

1. Bottom snake

2. Top snake

3. Middle snake

4. End snake

The correct answer is: Top snake

An electrically operated drain gun is an adaptation of the top snake because it is designed to clear drain clogs from the top of a pipe. The other options are incorrect because they either refer to types of snakes that are not operated by electricity or they refer to snake placements that are not typically used for removing drain clogs. For example, the bottom snake is a handheld tool with a crank, the middle snake is an auger, and the end snake typically extends horizontally from the side of a pipe.
