Who discovered insulin?

Matthew Evans and Henry Woodward
Sir Frederick Banting of Toronto and Charles Best
Alexander Graham Bell
Joseph-Armand Bombardier

The correct answer is: Sir Frederick Banting of Toronto and Charles Best

Insulin was discovered by Sir Frederick Banting of Toronto and Charles Best. Although it may seem tempting to choose A (Matthew Evans and Henry Woodward), they were actually researchers who created a pancreatic extract similar to insulin, but it was not as effective. Alexander Graham Bell (option C) is best known for inventing the telephone, and Joseph-Armand Bombardier (option D) is known for inventing the snowmobile, neither of which are associated with the discovery of insulin. Therefore, option B is the correct answer as it accurately identifies the individuals who discovered insulin.
