What does it mean to "succumb"?

The term "succumb" means to give in or yield to a superior force, typically after resisting or struggling against it. This often happens in situations where one faces overwhelming pressure, adversity, or temptation. The essence of the word implies a surrendering of one's will or strength in the face of challenges or influences that are too powerful to withstand.

In context, when an individual succumbs to an illness, it means that the illness has proven too strong for them to fight off successfully. This notion encapsulates the idea of yielding to forces that are formidable or insurmountable. Understanding "succumb" in this light clarifies that it is about giving in rather than resisting, leaving, or overcoming difficulties, which aligns with the correct answer.
