Yellow colour of faeces is on account of
(a) Excessive turmeric
(b) Bile
(c) Degradation product of heamoglobin
(d) None of the above

Options

A. Excessive turmeric
B. Bile
C. Degradation product of heamoglobin
D. None of the above

Answer

To determine the reason for the yellow color of feces, let's analyze the options provided in the question step by step.

### Step 1: Understand the Components of Feces
Feces are composed of various substances, including undigested food, bacteria, and waste products from the liver. The color of feces can be influenced by these components.

**Hint:** Consider what substances are produced by the liver and how they might affect color.

### Step 2: Analyze the Options
- **(a) Excessive turmeric:** Turmeric can impart a yellow color, but it is not a common component of feces for most individuals.

**Hint:** Think about how turmeric is consumed and its typical effects on the body.

- **(b) Bile:** Bile is produced by the liver and contains bile salts and pigments. The pigments in bile, particularly bilirubin and biliverdin, are derived from the breakdown of hemoglobin.

**Hint:** Recall the role of bile in digestion and its components.

- **(c) Degradation product of hemoglobin:** When hemoglobin is broken down, it produces bilirubin, which is then converted into bile pigments. These pigments are responsible for the yellow color in feces.

**Hint:** Consider how hemoglobin degradation relates to bile pigments.

- **(d) None of the above:** This option suggests that none of the previous options are correct.

**Hint:** Evaluate if any of the previous options could be the correct answer.

### Step 3: Conclusion
The yellow color of feces is primarily due to the presence of bile pigments, which are degradation products of hemoglobin. Therefore, the correct answer is:

**(c) Degradation product of hemoglobin.**

### Final Answer
The yellow color of feces is on account of (c) Degradation product of hemoglobin.
