Best Answer

Explanation:

  • The alimentary canal varies in size from one animal species to the next.
  • It's a long tube in which food goes through before being digested and absorbed.
  • From the oesophagus to the anus, the alimentary canal in humans is around 9 metres long.
  • This is primarily due to the small intestine's extended shape.
  • The small intestine makes up around two-thirds of the alimentary canal's length.
  • The length of the human alimentary canal will be 6 to 9 metres depending on the circumstances.
  • Therefore, the alimentary canal, often known as the digestive tract, is a vital part of human digestion. From the oesophagus to the anus, the alimentary canal is around 30 feet long.

Final Answer:

Hence the correct answer is option D: 6-9m.
