## **Core Concept**
The question pertains to the legal sections under the Indian Penal Code (IPC) or the Code of Criminal Procedure (CrPC) that allow police to arrest a person and request a medical examination without the individual's consent. This involves understanding the legal framework surrounding arrest and medical examination procedures.

## **Why the Correct Answer is Right**
Section 27 of the **Indian Evidence Act, 1872**, allows for the examination of a person accused of rape by a medical practitioner at the request of a police officer, without the accused's consent. This provision is crucial in collecting medical evidence in cases of sexual assault. The section specifically empowers the medical officer to examine the accused and report on the findings, which can be crucial for the investigation.

## **Why Each Wrong Option is Incorrect**
- **Option A:** Without the specific section details provided in the query, it's hard to directly refute this option. However, generally, sections not specifically related to medical examination or consent in the context of arrest would not provide such authority.
- **Option B:** Similarly, without specifics, one can't directly address why this is incorrect, but if it's not related to the examination of accused persons in the context of consent, it wouldn't apply.
- **Option C:** This could potentially be a distractor; if it does not directly pertain to the medical examination of an accused person without consent, it would be incorrect.

## **Clinical Pearl / High-Yield Fact**
A crucial point to remember is that in cases of suspected rape or sexual assault, **Section 375** of the IPC defines rape, and **Section 376** provides the punishment. Moreover, for medical examination, **Section 27 of the Indian Evidence Act** plays a pivotal role as it allows for the medical examination of the accused without their consent, aiding in the collection of evidence.

## **Correct Answer:** . Section 27.
