Since you haven't added neither the circuit nor the choices, I cannot give you a precise choice.
However, I can tell you how to detect current in the circuit.
A current in the circuit can be detected and measured using a device known as ammeter.
Ammeter is connected in series with the path of the current to be detected/ measured.
If the ammeter reads zero values, this means that no current is flowing in the circuit.
If the ammeter detects a value, this means that current is flowing in the circuit.
