From Faraday's Law
If is the current and Unparseable_latex_formula\Omega is the resistance of the wire loop, then
We integrate both sides with respect to time to obtain the amount of charge that flows past a given point in the wire:
where is some time before the wire loop was pulled out of the magnetic field and is sometime after. At , there is no magnetic flux through the loop, and at , the magnetic flux through the loop is . So,
Therefore, answer (A) is correct.
