The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "the oesophagus pierces the diaphragm and enters the abdominal cavity." - This is true. The oesophagus is a muscular tube that connects the throat to the stomach and passes through the diaphragm at a specific point called the esophageal hiatus. 2. **Understanding the Reason**: - The reason states that "peristaltic movement starts from the oesophagus." - This is also true. Peristalsis is the wave-like muscle contractions that move food down the digestive tract, and it indeed begins in the oesophagus after swallowing. 3. **Evaluating the Relationship**: - The assertion is true, and the reason is true as well. However, we need to determine if the reason is the correct explanation for the assertion. - While both statements are true, the reason does not explain why the oesophagus pierces the diaphragm. The piercing of the diaphragm is an anatomical feature, while peristalsis is a functional process that occurs after food is swallowed. 4. **Conclusion**: - Since both the assertion and the reason are true, but the reason does not correctly explain the assertion, the correct answer is: **Option B**: If both assertion and reason are true, the reason is not the correct explanation of the assertion.
