What is the percentage of water in lanolin?

Explanation:
Water content in lanolin is kept very low because lanolin is a lipid-rich wax; only a small amount remains as moisture. In pharmaceutical-grade lanolin, the typical water content is about 0.25% by weight. This small amount reflects its predominantly hydrophobic, waxy nature, where too much water would alter its consistency and performance in formulations. The other options describe much higher or much lower moisture levels that aren’t characteristic of lanolin, so 0.25% is the best match.
