A compass box and a dip circle were taken to magnetic north pole of earth. What would one observe with regard to the direction of their needles and why?

IF a magnetic compass and a dip circle are taken to the magnetic poles of the Earth, what would be the directions of their needle ? Explain giving reasons.

Assertion: If a compass needle be kept at magnetic north pole of the earth, the compass needle may stay in way direction. Reason: Dip needle will stay vertical at the north pole of earth.

Assertion: If a compass needle be kept at magnetic north pole of the earth, the compass needle may stay in any direction. Reason: Dip needle will stay vertical at the north pole of earth.

Direction. In the following questions, a statement of assertion is followed by a statement of reason. While answering a question, you are required to choose the correct are out of the given four responses and mark it as (A)If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if assertion is true, but reason if false, (D) if both assertion and reason are false Assertion : If a compass needle be kept at magnetic north pole of the earth, the compass needle may stay in any direction. Reason : Dip needle is vertical at the north pole of the earth.

If a compass needle be placed on the magnetic north pole of the earth, then how does it be have ? If a dip needle be placed at the same place, then what will be its behaviour?
