D Correct answer
Explanation

According to the answer choices here, the statement 1 is definitely the assertion. Now, Darwin might have proposed the theory but as far as the theory being a key to Earth's evolutionary years is concerned, Darwin has nothing to do with it and so the statement will be irrelevant to 1. This leaves us with answer choices (1) and (4). The statement 3 is in the same line as 1. So, it should be marked B. Hence, answer is (4).

AI explanation

Sentence 1 states the overall claim that natural selection drives evolution, making it the concluding Assertion (A). Sentence 2 (Darwin's fame) is a fact that doesn't argue for or against the claim, so it's Irrelevant (C); sentence 3 (species today support natural selection) directly backs the assertion, making it a Supporting reason (B); and sentence 4 suggests evolution might not depend on natural selection, directly opposing the assertion, making it the Counter-argument (D). This gives the sequence A, C, B, D.
