So brilliantly explained

Wrong. Bicep does not contract to initiate the tennis forehand. It is initiated by internal shoulder rotation. So I think that’s the class 2 lever.. ? However because the elbow leads the wrist that also is another lever. I’d be interested to see you break down the full kenetic chain from knee to wrist of tennis forehand.

There's absolutely more to a tennis forehand than elbow flexion - the intricacies of which are beyond the scope of this exam question, levels and exam board. As far as the mark scheme is concerned for this level of biomechanics, elbow flexion occurs during the strike/follow through phase, and the lever system present in this isolated movement is 3rd class, and caused (predominantly) by concentric bicep contraction.
