Assertion : Cuprous ion `(Cu^(+))` has unpaired electrons while cupric ion `(Cu^(++))` does not.
Reason : Cuprous ion `(Cu^(+))` is colourless where as cupric ion `(Cu^(+2))` is blue in the aqueous solution.

If both assertion and reason are true and the reason is not the correct explanation of the assertion.

If both assertion and reason are true but reason is not the correct explanation of the assertion.

If assertion is true but reason is false.

It the assertion and reason both are false.

Assertion : Cuprous ion (Cu^(+)) is colouless whereas cupric ion (Cu^(++)) is blue in the aqueous solution. Reason : Cuprous ion (Cu^(+)) has unpaired electrons while cupric ion (Cu^(++)) does not .

If both the assertion and reason are true and reason is correct explanation of the assertion .

If both the assertion and reason are true but reason is not a correct explanation of the assertion .

If the assertion is true but the reason is false.

If both assertion and reason are false.

Both have unparied electrons in d-orbital

Cuprous ions has imcomplete d-orbital and cupric ion has a completed d-orbital

Both have half-filled `p` and d-orbitals

Cuprous ion has a completed d-orbital and cupric ion has an incomplete d-orbital
