Answer 1

it's D) the intensity of magnetic field in A is less than in B ........

hope it will help you......✌☺️✌

Answer 2

To choose out suitable among the options

you need know about basic theory magnetic field intensity

Magnetic field intensity is directly proportional to amount of electric current passing through the conductor

here option B is right because parallel combination of resistor allow more current to flow than option A in which resistor is connected in series results in low amount of current to flow
