Wilhelm Réntgen

Luis Alvarez

Henry Moseley

William Crookes

Explanation:

- Option 1: Wilhelm Röntgen: He is known for discovering X-rays. His work revolutionized diagnostic medicine but did not involve dinosaur extinction theories.

- Option 2: Luis Alvarez: He proposed the theory that an asteroid impact led to dinosaur extinction. Alvarez and his team provided evidence, such as high iridium levels, to support this hypothesis.

- Option 3: Henry Moseley: His work in chemistry and physics, particularly the concept of atomic numbers, was groundbreaking. However, it wasn't related to dinosaur extinction.

- Option 4: William Crookes: He was known for his research in chemistry and physics, including the discovery of the element thallium. Crookes did not work on dinosaur extinction theories.
