Consider the following statements: Adjustment is required in an induction type energy meter in the following manner so that it can be compensated for slowdown of speed on the specified load due to some unspecified reason: 1. Adjusting the position of braking magnet and moving it away from the centre of the disc. 2. Adjusting the position of braking magnet and moving it closer to the centre of the disc. 3. Adjusting the load. Which of these statements are correct? (a) 1, 2 and 3 (b) 1 only (c) 2 only (d) 3 only
