Answer : The correct option is, (A) forms colorful compounds.

Explanation :

As we know that nickel (Ni) is transition metal with atomic number 28 and it is belong to the 3-d series in a periodic table.

The electronic configuration of 'Ni' is : [tex]1s^22s^22p^62s^23p^64s^23d^8[/tex]

It is a transition elements that has ability to shows variable oxidation state and due to variable oxidation state they forms colorful compounds.

Hence, the correct option is, (A) forms colorful compounds.
