The correct Answer is:
C
The formation of balcke precipitate indicates the presence of sulphur in an organic compound. The sodium extract of organic compound contaisn `Na_(2)` S which forms a blanc precipitate of PbS when treated with lead acetate.
`Na_(2)S+underset("Lead acetate")((CH_(3)COD)_(2) ) Pb to underset(("black ppt")) underset("Lead sulphide")(PbS darr) +CH_(3)CONa`
