Which word is best described as "extremely harmful or dangerous to health"?

Innocuous
Benign
Virulent
Harmless

The correct answer is: Virulent

The term that best describes something as "extremely harmful or dangerous to health" is "virulent." This word is often used in the context of diseases or pathogens, signifying a high level of toxicity or ability to cause severe illness. For example, a virulent strain of bacteria is one that can lead to serious health issues or even death, highlighting its extreme danger to health. The other terms provided convey very different meanings. "Innocuous" refers to something that is not harmful or offensive, while "benign" denotes a condition or quality that is gentle and not harmful, particularly in a medical context when describing tumors that do not invade surrounding tissues. "Harmless" clearly indicates something that poses no danger at all. Each of these alternatives emphasizes safety or lack of threat, which contrasts sharply with the harmfulness implied by "virulent."
