From Faraday's Law

If

is the current and Unparseable_latex_formula\Omega

is the resistance of the wire loop, then


, so

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,

So,

Therefore, answer (A) is correct.
