0\( a \mathrm{~K}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7}+b \mathrm{KCl}+c \mathrm{H}_{2} \mathrm{SO}_{4} \longrightarrow x \mathrm{CrO}_{2} \mathrm{Cl}_{2} \)
+ y \( \mathrm{KHSO}_{4}+z \mathrm{H}_{2} \mathrm{O} \)
The above equation balances when
(A) \( a=2, b=4, c=6 \) and \( x=2, y=6, z=3 \)
(B) \( a=4, b=2, c=6 \) and \( x=6, y=2, z=3 \)
(C) \( a=6, b=4, c=2 \) and \( x=6, y=3, z=2 \)
(D) \( a=1, b=4, c=6 \) and \( x=2, y=6, z=3 \)
