• A. True
• B. False
• C. It contains water
• D. It contains 10% coal tar

Answer: (A)

LCD, or Liquid Coal Tar Solution, is formulated by dissolving coal tar in an alcoholic solvent, typically at about 20% coal tar, with a small amount of polysorbate 80 to solubilize the tar. Coal tar is not readily soluble in water, so alcohol provides the solvent medium and polysorbate 80 helps keep the tar evenly dispersed and stable in solution. Because the composition relies on an alcohol base rather than water, the formulation does not contain water. The standard tar content is 20%, not 10%, so that option wouldn’t fit. Therefore, the statement is correct.
