The Correct Option is D
Solution and Explanation
- Arsenic sulphides (\({As}_2{S}_3\) and \({As}_2{S}_5\)) are known to be yellow in color.
- Lead sulphide (\({PbS}\)) and Copper sulphide (\({CuS}\)) are typically black in appearance.
- Ammonium sulphide (\({(NH}_4)_2{S}\)) is colorless or slightly yellowish but is not classified among the prominent yellow sulphides.
