Gangrene is best described as necrotic tissue infected by bacteria. Which option contains this definition?

Explanation:
Gangrene describes tissue that has died (necrosis) and is infected by bacteria. This combination—dead tissue that becomes infected—is what defines gangrene, and it helps explain why this term is used for conditions where blood flow is severely compromised and infection follows. The other terms don’t fit this description: hypoxia is just a lack of oxygen, which can lead to tissue damage but does not inherently define infection or necrosis; endogenous refers to processes arising from within the body; idiopathic means the cause is unknown. So the term that best matches “necrotic tissue infected by bacteria” is gangrene.
