Correct Answer: Option B
Explanation

NB:      1F = 1 mole of electrons of the atom of an element

In the case of copper (Cu), the valency is 2+.

⇒      Cu\(^{2+}\)  + 2e\(^-\) →  Cu

So,          2F = 1 mole of Cu

then,       2F = x mole

              x = \(\frac{2\times1}{2}\)

              x =  1 mole 

There is an explanation video available below.
