option "A" is the right answer (Question: 344020.0 )

I think the option "A" will be the right answer. Practically it vibrates violently and sometimes a 12V dc, 200rpm motor runs at a speed of 30-40 rpm when 12 ac is applied to it.

Options:
A)

the motor will vibrate violently

B)

the motor will run with less efficiency and more sparking
