The right answer is B.
Insulin is a hormone naturally secreted by the pancreas, specifically by specialized cells located in the islets of Langerhans. It allows glucose (sugar) to pass blood into the cells of the body. These will use glucose as energy or store it for future use.
In healthy subjects, insulin is secreted continuously. The body produces insulin according to the needs and foods consumed. For example, after a meal, the pancreas secretes additional insulin, allowing blood glucose to stay within normal limits.
Pride can be a positive trait as it helps an individual gain confidence in their work and skills, making them more successful and happier. However, pride can be negative as it may cause one to believe they are entitled to their success, and also may cause them to treat others inferiorly. Hope this helps! :)
