Ответ:
option c
Explanation:
A circuit contains a conducting wire and a voltage source. Current flows through a closed circuit. A circuit is said to be open if there is break in the circuit that is there is a disconnect such that current does not flow.
When the heroine cuts the wire, she actually breaks the circuit which means that she changed the closed circuit to an open circuit.
option c is correct.
