**Core Concept**
Forensic medicine is an interdisciplinary field that applies medical knowledge to the legal system. The study of death in all its aspects is a crucial component of forensic medicine, involving the investigation of causes, timing, and circumstances of death.

**Why the Correct Answer is Right**
The branch of forensic medicine that deals with the study of death in all its aspects is known as **Medico-Legal Autopsy** or **Forensic Pathology**. Forensic pathologists use their expertise in pathology, toxicology, and other medical sciences to examine deceased individuals, determine the cause and manner of death, and provide evidence for legal proceedings. This involves analyzing tissue samples, examining the body for signs of trauma or disease, and using various techniques such as toxicology and radiology to gather information.

**Why Each Wrong Option is Incorrect**
* **Option A:** Forensic Odontology is the study of the application of dental science to the identification of human remains and the analysis of bite marks. While it is a related field, it is not the study of death in all its aspects.
* **Option B:** Forensic Toxicology is the study of the analysis of toxic substances in biological samples, but it is a specific aspect of forensic science rather than the comprehensive study of death.
* **Option D:** Forensic Psychiatry is the study of the intersection of psychiatry and the law, but it does not involve the examination of deceased individuals.

**Clinical Pearl / High-Yield Fact**
The term "medico-legal" refers to the intersection of medicine and law, and is often used in the context of forensic medicine. In medico-legal autopsies, forensic pathologists must balance their medical expertise with the need to provide evidence for legal proceedings.

**Correct Answer:** C.
