**Core Concept**
The question pertains to the legal and ethical protocols surrounding postmortem examinations, specifically the procedure for handling the body after a postmortem has been conducted in a medico-legal context. This involves adhering to established guidelines to ensure the integrity of the investigation and respect for the deceased and their family.

**Why the Correct Answer is Right**
In a medico-legal dispute, the body is typically handed over to the police or the investigating authority for further examination and investigation. This is because the postmortem examination is conducted to determine the cause of death, which may be relevant to the investigation. The police or investigating authority may need to conduct additional investigations, such as collecting evidence or conducting further autopsies, to aid in their inquiry.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not relevant to the handling of the body after a postmortem in a medico-legal context. The family or relatives of the deceased may be involved in the process, but they are not typically responsible for handling the body.
