Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Biot-Savart law and Ampere's law, both help in finding magnetic field distributions, but Ampere's law takes symmetry into account as its a closed line integral (Amperian loop). Both laws can be used to calculate the net magnetic field produced at a point by various distributions of current.
