Explanation:

A thesis statement presents a debatable claim that guides an essay, rather than a factual statement. The first option makes a arguable claim about Marie Curie being the greatest scientist of her time, supported by specific points. The second option is a verifiable historical fact, not a thesis.

Answer:

Marie Curie's experiments with radioactivity, discovery of two elements, and work as a physics professor made her the greatest scientist of her time.
