Which term best defines something that is poisonous or toxic?

Plausible
Vivid
Virulent
Segments

The correct answer is: Virulent

The term that best defines something that is poisonous or toxic is "virulent." This word is often used to describe harmful pathogens or substances that can cause disease or harm, emphasizing their ability to produce serious effects. In a broader context, "virulent" conveys the idea of something being highly infectious or extremely dangerous, particularly in relation to biological threats. While "plausible" refers to something that seems reasonable or probable, and "vivid" describes something that is strikingly intense or colorful, these terms do not relate to toxicity. "Segments," on the other hand, denotes portions or parts and is unrelated to the notion of being poisonous. Therefore, "virulent" is the most accurate choice to denote something with toxic characteristics.
