Answer

**Step-by-Step Solution:**

1. **Understanding the Alimentary Canal**: The alimentary canal, also known as the digestive tract, is a long tube that extends from the mouth to the anus. It plays a crucial role in the digestion and absorption of food.

2. **Identifying the Length**: The length of the human alimentary canal is typically measured in meters. It is important to note that the length can vary among individuals, but there is a general average.

3. **Conversion of Feet to Meters**: In the video transcript, it is mentioned that the alimentary canal is approximately 30 feet long. To convert feet to meters, we can use the conversion factor where 1 foot is approximately 0.3048 meters. Therefore, 30 feet is approximately 30 x 0.3048 = 9.144 meters.

4. **Choosing the Correct Option**: Based on the information provided, the length of the human alimentary canal is about 9 meters. Among the options given (100 cm, 3-4 m, 4-6 m, or 6-9 m), the most appropriate choice is 6-9 m.

5. **Final Answer**: The length of the human alimentary canal is approximately 6 to 9 meters.
