The correct choice is (b) The current that flows through connection wires is called conduction current
For explanation I would say: The true statement is ➔ the current that flows through the connection wires is called conduction current. All the other statements are not valid. Displacement current and conduction current can numerically be equal. During charging of the capacitor, in the connection wires, conduction current is continuous and displacement current is discontinuous. Similarly, during the charging of the capacitor, in the gap between the capacitor plates, conduction current is discontinuous and the displacement current is continuous.
