Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Antoine Lavoisier.
The theory of combustion as a chemical reaction with oxygen in the 18th century, which excluded the phlogiston theory, was developed by Antoine Lavoisier. Lavoisier is often referred to as the "Father of Modern Chemistry" for his groundbreaking work. He demonstrated that combustion involves the reaction of a substance with oxygen, leading to the release of heat and light, and he helped disprove the phlogiston theory. His work laid the foundation for the modern understanding of chemical reactions and the law of conservation of mass.
