Correct Answer

Option B — छोटी आंत

Detailed Solution & Explanation

The correct answer is छोटी आंत (small intestine).

Key Points

• The small intestine is the longest part of the human digestive tract, roughly 6-7 metres long, against about 1.5 metres for the large intestine.
• It has three sections: duodenum, jejunum and ileum, and is where most digestion and absorption occur.

Additional Information

• Its inner surface carries villi and microvilli, which enormously increase the absorptive area.
• The liver is the largest gland; the skin is the largest organ; the femur is the longest bone.
