Question

Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : Full thickness prolapse of rectum includes protrusion of all the layers of rectal wall, and is usually associated with a weak pelvic floor.
Reason (R) : The Rectal prolapse is thought to commence as an intussusception of the rectum, which descends to protrude outside the anus.
In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is NOT the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

Rectal prolapse = full wall protrusion + starts as intussusception — both facts fit together for diagnosis.

Answer 1

The Correct Option is A

Assertion (A) is correct because a full thickness rectal prolapse involves the protrusion of all layers of the rectal wall through the anal canal.
This condition is commonly linked to pelvic floor weakness, which contributes to the failure of support structures.
Reason (R) is also correct — rectal prolapse typically begins as an intussusception of the rectum, which progresses downward and eventually protrudes externally.
This explains the mechanism behind the full thickness prolapse described in (A).
Therefore, both the Assertion and the Reason are correct, and (R) correctly explains (A).
So, option (1) is the right answer.
