  • A Glomerulus
  • B Urea
  • C Faeces
  • D Carbon Dioxide
  • E Bowman's capsule
Correct Answer: Option C
Explanation:
The correct answer is:

C. Faeces

Explanation:
Excretion is the process of removing metabolic wastes produced inside the body, such as:

- Urea (from the liver, removed by kidneys)
- Carbon dioxide (from respiration, removed by lungs)
- Structures like the glomerulus and Bowman's capsule are involved in filtering waste in the kidneys.

However, faeces are not metabolic waste — they are undigested food residues eliminated through egestion, not excretion.
