A mixture consists of two metal oxides A (green) and B (white). Mixture was dissolved in `20 mL 2M NaOH` solution contraining some `H_(2)O_(2)` to give a clear yellow solution leaving no residue. The above solution was separated into two parts. One part was acidified with acetic acid and then treated with `(CH_(3)COO)_(2)Pb` solution to give an yellow precipitate (C). C dissolves in dilute nitric acid forming a clear orange solution. Other part of solution was acidified with `2.0 M HCl` and the `2M NH_(3)` was added till the solution became alkaline and finally boiled. A white gelatinous precipitate (D) was obtained. D was then dissolved in dilute `HCl` and `6.0 M` ammonium acetate was added. The solutions was finally treated with a few drops of alumiun reagent and made basic by adding ammonium carbonate. A red precipitate was obtained. Answer the following three questions based on the above information.
Compound D is most likely

A

`Fe(OH)_(3)`

B

`Cr(OH)_(3)`

C

`Pb(OH)_(2)`

D

`Al(OH)_(3)`
