Which of the following poses a problem for the prototype view of concepts?

A) an inability to explain the typicality effect
B) an inability to explain why people have a hard time providing strict definitions of their concepts
C) an inability to explain why some classifications are easy to make and others are unclear
D) an inability to explain why the typicality of a particular instance can depend upon context

The prototype view of concepts suggests that people categorize objects and ideas by comparing them to an "average" or "typical" example of a category (the prototype). However, it struggles to account for how context can influence what is considered a typical instance, as people's perceptions of what is typical can change based on the situation or context, which is not easily explained by a static prototype model.
