Title 40 CFR addresses which broad area?

• A. Drinking water compliance.
• B. Wastewater testing.
• C. The protection of the environment as administered by the EPA.
• D. Occupational safety regulations.

Answer: (C)

The main idea here is recognizing what Title 40 of the Code of Federal Regulations covers and which agency oversees it. Title 40 is all about environmental protection at the federal level, with rules and standards put forward by the Environmental Protection Agency to safeguard air, water, land, and ecosystems. That broad focus on protecting the environment and enforcing environmental laws is why this option is the best fit. The other ideas point to specific environmental programs (like drinking water compliance or wastewater testing) or to areas outside the EPA’s remit (occupational safety regulations), which is why they don’t describe Title 40 as a whole.
