Answer: A. Touch free faucets and towel dispensers
Explanation:
A faucet is a device by which a liquid or gas can be drawn from a container or pipe. The flow of liquid or gas can be controlled by the faucet. A touch-free faucet will provide clean water without any contamination. This will prevent water-borne diseases and the water can be used for the purpose of drinking, washing, and bathing. The towel dispensers will provide a dust-free towel and hence, will prevent dust-related allergies and respiratory diseases.
Thus option A will provide a healthy environment.
