Answer
B. compass deflection
Explanation
In the 19th century, scientists discovered the relationship between electricity and magnetism through various experiments and observations. One key observation was the deflection of a compass needle when placed near a current-carrying wire, which demonstrated the magnetic effect of electric currents. This phenomenon was crucial in understanding electromagnetism. Additionally, the operation of electric motors, which convert electrical energy into mechanical energy, further illustrated the interplay between electricity and magnetism. While cell diversity is unrelated to this discovery, both compass deflection and electric motor operation are directly relevant.
