Solution

The correct option is C zero
Given
An infinitely long cylinder is kept in z axis
Magnetic field is also in z Axis
Solution
Since magnetic field is constant and there is no change in the magnetic flux associated with it, therefore there will be no induced emf and current.

The correct option is C
