Final answer:
The correct answer is C. Water- and fire-resistant.
Step-by-step explanation:
The correct answer is C. Water- and fire-resistant. Although hard hats are typically designed to be resistant to penetration from sharp objects, color-coded for different types of work, and provide printed instructions for suspension adjustment and replacement, they are not necessarily water- and fire-resistant. This is because hard hats primarily serve the purpose of protecting the wearer's head from falling objects and potential impact, rather than fire or water hazards. It is important to choose a hard hat that meets the specific safety requirements of the job or workplace.
