When giving help, what matters is your own safety. If you touch the victim while the wire is on them, you will get an electric shock too, so first you must remove the wire with an insulating object.
In any emergency, the rescuer's safety comes first. Since the victim is in contact with the wire, touching them directly would give you an electric shock. Before giving any medical help, you must first remove the wire with some non-conducting, insulating object.
Option 1. Touching the victim while they are still in contact with the wire will immediately give you an electric shock.
Option 2. You cannot safely carry out an initial examination until the electrical danger has been completely removed.
Option 4. Looking for burns is a much later step: the immediate task is to break the electrical contact safely.
