Choose the correct answer from the options given below :

Consider the following reactions

$\mathrm{Na_2B_4O_7} \xrightarrow{\Delta} 2X + Y$

$\mathrm{CuSO_4} + Y \xrightarrow{\text{Non-Luminous flame}} Z + SO_3$

$2Z + 2X + \text{Carbon} \xrightarrow{\text{Luminous flame}} 2Q + \mathrm{Na_2B_4O_7} + CO$

The oxidation states of Cu in Z and Q, respectively are :
