I’d go with B) Abduction. It’s key for scapulohumeral rhythm.

I feel a bit confused; I thought all these movements could relate to scapulohumeral rhythm, but I guess abduction is the most relevant?

I practiced a similar question, and I think it was about testing shoulder movements. Abduction seems like the most logical choice to me.

I'm not entirely sure, but I remember something about how internal and external rotation might not really test the rhythm as effectively as abduction or adduction.

I think it might be abduction since it involves the movement of the arm away from the body, which could help assess scapulohumeral rhythm.
