Which statement best describes cryonics?

• A. Senotherapeutics
• B. Cellular rejuvenation
• C. Caloric restriction
• D. Cryonics

Answer: (D)

Cryonics is the practice of preserving a human body or brain at extremely low temperatures after death, with the hope that future technology will allow revival. This typically involves rapid cooling and vitrification to reduce damage, then long-term storage in cryogenic facilities. The other terms point to different aging or life-extension ideas: senotherapeutics are drugs that target senescent cells; cellular rejuvenation refers to restoring youthful cell function; caloric restriction involves lowering calorie intake to slow aging. Because the description here matches the idea of freezing and preserving tissue for possible future revival, cryonics is the best fit.
