Which phrase expresses that once a species is extinct, it cannot be recovered?

Which phrase expresses that once a species is extinct, it cannot be recovered?

• A. Extinction Is Forever
• B. Permanent Loss
• C. Irreversible Extinction
• D. Endangered But Recoverable

Answer: (A)

The main idea is that once a species is extinct, there are no living individuals anywhere, so there’s no natural way to bring it back. Extinction Is Forever expresses that permanence directly, using “forever” to signal there won’t be a future recovery in the natural world. The other phrases fall short for different reasons: Permanent Loss conveys lasting damage but doesn’t name extinction itself; Irreversible Extinction is true but clunkier and redundant since extinction already means no recovery; Endangered But Recoverable describes a situation where recovery is possible, which is the opposite of extinction.
