Classic FA Mnemonic:

S1-S1 Buckle my Shoe (foot) L3-L4 Kick the Door (leg) C5-C6 Pick up Sticks (bicep) C7-C8 Lay them Straight (tricep)

I know it's a reflex mnemonic, but it's served me well in these sorts of questions.

If knee is mentioned just look for L4 and then rule out all the other options, you are left with just one option just pick it and don't think beyond.
