Magnetic Field Of Coaxial Cable

The word coaxial means same axis. So for a long straight cable to be coaxial, it must have concentric cylindrical shaped conductor around it. Coaxial cable (popularly called ‘coax’) has various applications ranging from current conductors to radiofrequency signal transmitters. This cable has lower emission losses and provides protection from electromagnetic interference which allows signals with less power to transmit over longer distances.For example, currents produced in the pickup of a stereo turntable generally travel to the amplifier through a coaxial cable.The self-inductance of a coaxial cable is another important characteristic, because it influences the propagation of electrical signals in the cable.

Question

Consider the circuit in the diagram below.
eeee
The switch at the top is moved to the closed or on position, the lightbulb glows brightly for a moment, and then dims gradually until it is fully
dark. The switch on the top leg is then moved to the open or off position. The switch on the central leg is then moved to the closed or on
position. What would happen to the bulb.

b
с
d
The light bulb would light up and stay constant.
The light bulb would gradually brighten.
The light bulb would light up and gradually dim.
The light bulb would flash on and then immediately shut off.
