Motor A and B are in parallel and therefore they have the same voltage of the power supply and therefore it should be connected parallel to the motors.

I hope I helped.

True.
and for the voltmeter, remeber this: VOLTMETER IS ALWAYS CONNECTED IN PARALLEL TO WHAT YOU NEED TO FIND ITS VOLATAGE.
you will never find a voltmeter connected in series, and if u found one, then in it will be in paper1, and ofc it is a wrong answer
Voltmeter in parallel

Listen, I'm going to give you some advice. A lot of the queries you have seem to be very very basic. If you picked up your textbook and refreshed your concepts you'd be a lot better at physics.

IGCSEs aren't ONLY about past papers.
