I had been asked this question by my school principal while I was bunking the class.

Origin of the question is Induction Motors in section Braking of DC Motors & Induction Motors of Electric Drives

Answer 1

The correct answer is (a) more than the transformer

To explain: The magnetizing current in the induction motor is (23-25)% of the full load current. The magnetizing current in the transformer is 3-5% of the full load.
