What was the significance of the discovery of insulin by Sir Frederick Banting and Charles Best?

  1. Starting a business

  2. Saving lives

  3. Creating a new sport

  4. Inventing the telephone

The correct answer is: Saving lives

This is because the discovery of insulin by Sir Frederick Banting and Charles Best revolutionized the treatment of diabetes and saved countless lives. Insulin is a hormone that regulates blood sugar levels and is essential for individuals with diabetes to lead a healthy life. Prior to the discovery of insulin, diabetes was a deadly disease with little hope for effective treatment. The other options are incorrect because they are unrelated to the contributions of Banting and Best. Starting a business, creating a new sport, and inventing the telephone had no direct correlation to the discovery of insulin and its impact on the treatment of diabetes.
