Liver secretes bile containing substances like bilirubin, biliverdin, cholesterol, degraded steroid hormones, vitamins and drugs. Most of these substances ultimately pass out along with 

Options

A. UrineÂ
B. Digestive wastesÂ
C. Sweating
D. Secretion of sebum

Explanation

To answer the question, we need to understand the role of the liver and the substances it secretes in bile, as well as how these substances are ultimately eliminated from the body.

### Step-by-Step Solution:

1. **Identify the Substances in Bile**: The liver secretes bile that contains various substances such as bilirubin, biliverdin, cholesterol, degraded steroid hormones, vitamins, and drugs. These substances are byproducts of metabolism and are not needed by the body.

2. **Understand the Process of Excretion**: The body needs to eliminate waste products to maintain homeostasis. The substances secreted in bile are considered waste and must be excreted from the body.

3. **Determine the Pathway of Excretion**: The primary pathways for excretion of waste substances include urine and feces. While urine primarily eliminates nitrogenous wastes (like urea and uric acid), bile components are generally not excreted through urine.

4. **Identify the Correct Excretory Route**: Most of the substances present in bile, such as bilirubin and other bile pigments, are ultimately excreted through the digestive system. They are passed out of the body along with feces.

5. **Conclusion**: Therefore, the substances secreted by the liver in bile ultimately pass out of the body along with feces.

### Final Answer:
Most of these substances ultimately pass out along with **feces**.
