my girl said biceps/triceps (is labelled as one letter) & the other one is the fulcrum - the elbow. So it is P & R?

I think so

The Question is:
The diagram shows a man exercising by raising a dumbell. Which of the following are needed for this action?
a) The biceps and the triceps
b) The elbow
c) The lower arm (bone)

My answer: All of the above.
Reason: The lower and upper arms are like levers. The elbow is the fulcrum, the muscles apply the effort and the lower arm is part of the lever. So, you need all three!
