To have no external behavioral or physiological signs of life __________.

• A. may be taken as evidence of being 'clinically dead'
• B. is the same as legal death
• C. confirms brain death
• D. means the person is in a coma

Answer: (A)

Absence of external behavioral or physiological signs of life is used to infer clinical death. When the body ceases circulating and breathing, and there are no observable responses or life signs, clinicians may determine that a person is clinically dead. This designation focuses on the loss of cardiac and respiratory functions rather than on the status of the brain. It’s important to distinguish clinical death from brain death, which requires specific testing showing irreversible loss of all brain activity and is often the criterion used for legal death in many places. A coma, on the other hand, is a state of impaired consciousness where some brain activity and reflexes may remain. So, no signs of life generally points to clinical death, which is why that option is the best fit.
