Which option correctly matches the scientist with the law?

Answer and explanation

Correct answer: Richter and the law of reciprocal proportions

The correct historical association is Richter with the law of reciprocal proportions. This law states that if two elements combine separately with a fixed mass of a third element, the masses of the first two elements are related to each other in the same or a simple multiple of the ratio in which they combine directly. Therefore, option C is correct. Lavoisier is chiefly associated with conservation of mass, not definite proportions. Proust is associated with definite proportions, and Dalton is associated with multiple proportions. Gay-Lussac is known for the law of combining gaseous volumes, so option D also mismatches the scientist and law.
