**Core Concept**
Exhumation is the process of digging up a corpse from a grave, often for forensic or medical examination. This procedure requires careful consideration of various factors, including legal and ethical aspects, to ensure that it is conducted with respect and dignity.

**Why the Correct Answer is Right**
Exhumation is typically performed when a body is suspected to have died under suspicious or unnatural circumstances. The process involves carefully excavating the body, usually with the assistance of a medical examiner, coroner, or other authorized personnel. This is often necessary to determine the cause of death, collect evidence, or perform further analysis on the body. The exhumation process must be conducted in a way that minimizes damage to the body and adheres to local laws and regulations.

**Why Each Wrong Option is Incorrect**

**Option B:** Exhumation requires a court order. **Incorrect because** while a court order may be necessary in some cases, it is not always a requirement for exhumation. Local laws and regulations can vary, and in some instances, exhumation may be permitted with the consent of the family or other authorities.

**Option C:** Exhumation is always a traumatic experience for the family. **Incorrect because** while exhumation can be emotionally challenging for family members, it is not always the case. Some families may choose to participate in the exhumation process as a way to gain closure or to ensure that their loved one receives a proper burial.
