An inductive probe is a point level measuring instrument consisting of a sealed probe containing a $q,$

A$.$ resistor

B$.$ coil

C$.$ capacitor

D$.$ all of the above

$A(n)q,$ is a point level measuring system consisting of a circuit of two or more probes or electrodes, or an electrode and the vessel wall where the material in the vessel completes the circuit as the level rises in the vessel.
