Which is an example of internal conflict?

a. a knight in shining armor fights a fire breathing dragon

b. a nervous actor tries to conquer his stage fright

c. a lone traveler struggles to survive in the wilderness

d. a dog and cat must learn to work together

The answer here would be B. A nervous actor tries to conquer his stage fright. This battle that the actor is faced with is pitting him against himself. The conflict is happening within the actor's mind/body.

In A, the knight is fighting another being, the dragon.

In C, the traveller is trying to survive in (against) the wilderness

In D, the dog and the cat are learning to work together, but they are not fighting themselves.
