• B. end Carboniferous
• C. end Permian
• D. early Devonian

Hint:

The end Permian mass extinction is the largest extinction event in Earth's history, significantly reducing biodiversity.

Answer 1

The Correct Option is C

Step 1: Understanding mass extinction events.
The end Permian extinction is the largest mass extinction event in Earth's history, occurring about 252 million years ago. It wiped out nearly 90% of all marine species and 70% of terrestrial species.

Step 2: Analyzing the options.
(A) end Silurian: This is incorrect as the end Silurian event was relatively minor.
(B) end Carboniferous: This is incorrect, as no major mass extinction occurred at the end of the Carboniferous period.
(C) end Permian: This is the correct answer as the end Permian is known for the greatest mass extinction event in Earth's history.
(D) early Devonian: This is incorrect, as the Devonian extinction was not as severe as the Permian event.

Step 3: Conclusion.
The correct answer is (C) end Permian.
