To make red lead, which compound is used?

Explanation:
Red lead is formed by oxidizing litharge, which is lead(II) oxide (PbO). When litharge is heated in air, it reacts with oxygen to produce lead tetroxide (Pb3O4), the red pigment. So the starting compound used to make red lead is litharge. The other options aren’t feedstocks for producing red lead: fisheye is a paint defect, a special thinner is a solvent, and red lead itself would be the product rather than the starting material.
