Battery E. None of the above

The correct answer is: D. Battery

Batteries contain hazardous materials that can pollute the environment if they are not disposed of properly. The EPA has established guidelines for the safe disposal of batteries, and it is important to follow these guidelines to protect the environment.

The other options are not required to be disposed of according to EPA guidelines. Keyboards, system boards, and power supplies can be disposed of in the regular trash. However, it is important to recycle these items whenever possible, as they contain valuable materials that can be reused.

Batteries should be recycled or disposed of at a hazardous waste collection site. Do not throw batteries in the trash, as they can leak harmful chemicals into the environment.
