Ans 1:

Ayush Gorain from Sarala Birla Public School, Ranchi
Class : Class 8
According to Faraday's right hand rule, electricity flowing from point A to B generates a magnetic field around the wire moving from right to left (above the wire), and left to right (below the wire). Due to the compass being above the wire (according to the question), the compass needle must be influenced by the magnetic field, such that it points towards the right; i.e. the needle points in a direction from left to right. Thus, I opine that option (A) is the correct answer, not option (D). As there is an electric current, there must be a magnetic field, and thus there must be a deflection in the compass, which excludes option (D) entirely.
