Answer

Brief Explanations:

The first right - hand rule in electromagnetism is used to relate the direction of current and the direction of the magnetic field. When you curl the fingers of your right hand in the direction of the magnetic field lines around a current - carrying wire, your thumb points in the direction of the current. So it relates current (thumb) to magnetic field (fingers).

Answer:

A. current (thumb) to magnetic field (fingers)
