Yellow colour of faeces is due to
(a) yellow foods
(b) bile pigments
(c) degradation products of haemoglobin
(d) excessive diet of turmeric

Options

A. yellow foods
B. bile pigments
C. degradation products of haemoglobin
D. excessive diet of turmeric

Explanation

To determine the reason for the yellow color of feces, we can analyze the options provided:

1. **Understanding the Options**:
- (a) Yellow foods: While yellow foods may contribute some color to the diet, they do not directly cause the yellow color of feces.
- (b) Bile pigments: Bile pigments, specifically bilirubin, are produced by the liver and are known to contribute to the color of feces.
- (c) Degradation products of hemoglobin: Bilirubin, a bile pigment, is a degradation product of hemoglobin, and it is responsible for the yellow color in feces.
- (d) Excessive diet of turmeric: Although turmeric is yellow, it does not significantly affect the overall color of feces.

2. **Analyzing the Correct Answer**:
- The yellow color of feces is primarily due to bile pigments, particularly bilirubin, which is a breakdown product of hemoglobin. This means that option (c) is correct, as it directly relates to the source of the bile pigments.

3. **Conclusion**:
- Therefore, the yellow color of feces is due to the degradation products of hemoglobin, specifically the bile pigment bilirubin.

**Final Answer**: (c) degradation products of hemoglobin.
