Answer: III and IV
Explanation:
- Cholesterol is a precursor to steroid hormones such as androgens (testosterone, progesterone, estradiol etc) because they all have the sterane ring present in cholesterol
- bile acids, taurocholate and glycocholate are derivatives of cholesterol that have organic compounds taurine and glycine fused to them respectively.
On the other hand, prostaglandins and vitamin K are not derived from cholesterol but made from polyunsaturated fatty acids and quinones respectively.
Thus, cholesterol is a precursor to steroid hormones and bile salts only
