Slip rings and brushes are found in:a)Wound rotorb)Squirrel cage rotor...
In squirrel cage type rotors, the rotor bar is permanently shorted at the end of the ring. Hence slip rings and brushes are not present in these type of rotors
Slip rings and brushes are present in wound type rotor

Option A is correct because in wound rotor ,the supply is given (or)resistance added(in case of induction type for improving starting torque.)to the rotor through sliprings and brushes.
whereas in squirrel cage type windings are shorted with endrings.so no need of sliprings and brushes.
