In step-III if \( \mathrm{Pb}\left(\mathrm{CH}_{3} \mathrm{COO}\right)_{2} \) is added without acidifying the solution with \( \mathrm{CH}_{3} \mathrm{COOH} \) then possible product may be:
(A) \( \mathrm{PbCrO}_{4} \)
(B) \( \mathrm{Na}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7} \)
(C) \( \mathrm{Na}_{2} \mathrm{CrO}_{4} \)
(D) \( \mathrm{Na}_{2} \mathrm{PbO}_{2} \)
