a. The molecule is not lipid soluble b. The molecule is not derived from a series of steps beginning with cholesterol

Explanation:

All the steroid hormones have a four ring sterol nucleus in their structure. These hormones are soluble in lipids. Steroid hormones are produced by the pathways using cholesterol as the starting substance. Some of the examples of steroid hormones are aldosterone, calcitriol, estrogens, and progesterone. Therefore, if the given molecule is not soluble in lipids and is not derived from cholesterol, it cannot be a steroid hormone.
