How many distinct anti-exposure coverall types are described?

• A. Four
• B. Nine
• C. Seven
• D. Five

Answer: (C)

You’re being asked to recall how many distinct anti-exposure coverall configurations the material describes. The text lists seven separate configurations, each defined by a different combination of features (for example, hood presence, whether boot covers are integrated or separate, how seams are sealed, whether the suit is disposable or reusable, and the protection level). Because seven distinct configurations are described, seven is the correct answer. The other numbers don’t match the actual count given in the material.
