In clinical and anatomical terminology, the term "cadaver" refers to:

Introduction / Context:
Medical and anatomical sciences use specific terms to describe patients, subjects, and bodies. One of the most frequently used terms in anatomy laboratories and forensic science is cadaver. Understanding this term is important for medical students, healthcare professionals, and anyone studying human anatomy because it clearly distinguishes between living subjects and deceased bodies used for study. This question asks you to select the correct definition of cadaver in a clinical and anatomical context.

Given Data / Assumptions:
• The word under consideration is cadaver. • Options describe living humans, a dead body used for anatomy, a living experimental subject, and a resurrected body. • Standard usage in medical education and forensic practice is assumed.

Concept / Approach:
A cadaver is a dead human body that is used for scientific study, especially for dissection in medical and dental colleges or for forensic examination. Individuals often donate their bodies for these purposes. Living human beings, whether ordinary patients or volunteers in clinical trials, are never called cadavers. The idea of a resurrected body belongs to religious or mythological discussions and is not a scientific term. Therefore, the correct definition must emphasize that a cadaver is a dead human body used for anatomical or scientific study.

Step-by-Step Solution:
Step 1: Recall that cadaver dissection is a key part of learning human anatomy in medical education. Step 2: Understand that the term is used only after death, not for living individuals. Step 3: Compare each option and locate the one that mentions a dead human body used for anatomy. Step 4: Eliminate options that clearly talk about living people or non scientific ideas such as resurrection. Step 5: Choose the option that best matches the standard clinical and anatomical definition.

Verification / Alternative check:
Medical textbooks, ethics statements about body donation, and educational guidelines consistently refer to cadavers when discussing the bodies used in dissection halls. Terms such as cadaveric organ donation also emphasize that the donor is deceased. You will not find living participants in any medical study being labeled as cadavers. This consistent usage across medical literature verifies that a cadaver is a dead human body used for scientific study.

Why Other Options Are Wrong:
Option A is incorrect because a living human being is called a patient, person, or subject, not a cadaver. Option C is incorrect because even if a person volunteers for a trial, the person is alive and is never termed a cadaver. Option D is incorrect because a resurrected human body is a concept from religion or fiction, not a scientific or clinical term.

Common Pitfalls:
Some learners may confuse the general words corpse, body, and cadaver. While all can refer to a dead person, cadaver is specifically used in contexts of education and scientific research. It is also important to remember the sensitivity and ethical respect that accompany the use of cadavers in teaching. Recognizing this precise meaning helps avoid misunderstandings in medical and forensic discussions.

Final Answer:
In clinical and anatomical terminology, a cadaver is a dead human body used for anatomical study and dissection.
