Someone help???

Decide whether the two events are disjoint and tell why or why not:
• randomly choosing a scarf that is blue
• randomly choosing a scarf that is frayed

A: Not disjoint, because the events cannot occur at the same time.

B: Disjoint, because the events cannot occur at the same time.

C: Disjoint, because the events can occur at the same time.

D: Not disjoint, because the events can occur at the same time.
