Answer: Option (B) is the correct answer.
Explanation:
It is known that flow of electrons is known as current. Also, we know that electrons carry a negative charge.
Therefore, when parallel wires carrying current in the same direction then due to the same charge there will be repulsion between the electrons.
Thus, we can conclude that Ampere showed that parallel wires carrying current in the same direction would repel each other.
