At standstill the equivalent of the 3-phase induction motor is similar

1.	At standstill the equivalent of the 3-phase induction motor is similar to _________(a) short-circuitedtwo winding transformer(b) open circuit two winding transformer(c) stand still synchronous motor(d) none of the mentionedThis question was addressed to me in an interview for internship.I'd like to ask this question from Equivalent Circuit in chapter Induction Machines of Electrical Machines
Answer» CORRECT option is (a) SHORT-circuitedtwo winding transformer Explanation: For s=1 at standstill, so it same as the short CIRCUIT of the transformer for the INDUCTION MOTOR.
