B Correct answer
Explanation

Ethylene is a natural plant hormone that triggers and regulates the fruit ripening process. It acts as a chemical signal that stimulates the production of enzymes which break down cell walls and convert starches to sugars, making fruits softer and sweeter. Commercially, fruits are exposed to ethylene gas to accelerate and control ripening.
