Explanation

Louis Pasteur developed pasteurization, but Nicolas Appert discovered the principle of canning (preserving food in sealed containers), which is a form of sterilization. However, 'Pasteurization' is often incorrectly attributed to him in some contexts, but strictly speaking, Appert's work is the foundation of canning/sterilization. Wait, let me double check. Appert is known as the father of canning. The process involves heating food in sealed containers to kill microorganisms, which is sterilization. Pasteurization is named after Pasteur and involves lower temperatures. So B is correct.
