Which term means good health and cleanliness?

• A. Impaired
• B. Impervious
• C. Incidence
• D. Hygiene

Answer: (D)

Hygiene is the term that means good health and cleanliness. It refers to practices and conditions that promote cleanliness and prevent illness, such as regular handwashing, bathing, oral care, and a clean living environment. The other options don’t fit: impaired describes reduced function, impervious means not allowing passage or not affected, and incidence refers to the rate of new cases. In health contexts, hygiene is the word that links cleanliness with maintaining health.
