Given below are two statements :
Statement I: Aluminium upon reaction with NaOH forms $[Al(OH)_6]^{3-}$ ion.
Statement II: The geometry of $ICl_4^-$, $ClO_3^-$ and $IBr_2^-$ is square planar, pyramidal and linear respectively.
In the light of the above statements, choose the correct answer from the options given below :

Consider the following reactions
$\mathrm{Na}_{2} \mathrm{~B}_{4} \mathrm{O}_{7} \xrightarrow{\Delta} 2 \mathrm{X}+\mathrm{Y}$
$\mathrm{CuSO}_{4}+\mathrm{Y} \xrightarrow{\text { Non-Luminous flame }} \mathrm{Z}+\mathrm{SO}_{3}$
$2 \mathrm{Z}+2 \mathrm{X}+$ Carbon $\xrightarrow{\text { Luminous flame }} 2 \mathrm{Q}+\mathrm{Na}_{2} \mathrm{~B}_{4} \mathrm{O}_{7}+\mathrm{CO}$
The oxidation states of Cu in Z and Q, respectively are :
