It is known that both the poles of a magnet $(north\ pole\ and\ south\ pole)$ have the same magnetic strength. So, the amount of the iron filings clinging to the North pole is almost equal to the south pole, when a magnet bar is immersed in the heap of the iron filings.

So, option $(a)$ is correct.
