We want to identify which among the listed sulfides are yellow in color:

$\mathbf{(NH_4)_2S}$

Ammonium sulfide is typically encountered as an aqueous solution that can be colorless to slightly yellowish in solution form. It is not known as a distinct “yellow sulfide” compound in the same sense as solid colored sulfides like orpiment (see below).

$\mathbf{PbS}$ (lead(II) sulfide)

$ \text{PbS} $ (Galena) is well-known to be black or grayish‐black in color.

$\mathbf{CuS}$ (copper(II) sulfide)

$ \text{CuS} $ is black (covellite).

$\mathbf{As_2S_3}$ (arsenic(III) sulfide)

$ \text{As}_2\text{S}_3 $ (orpiment) is characteristically yellow.

$\mathbf{As_2S_5}$ (arsenic(V) sulfide)

$ \text{As}_2\text{S}_5 $ is also typically a yellow sulfide.

Hence, among the options given,

$\mathbf{(D)}\;As_2S_3$ and

$\mathbf{(E)}\;As_2S_5$

are the two yellow inorganic sulfides.

Correct Choice

$ \boxed{\text{(D) and (E) only.}} $
