Which among these is not an advantage of polymorphism?

Code reusability
Improved code organization
Faster execution time
Extensible programs

The correct answer is: Faster execution time

Polymorphism generally refers to the ability of code or objects to take on different forms depending on the context. It allows for flexibility and adaptability, making it easier to modify and extend programs. A and B are advantages of polymorphism as it allows for code to be reused and organized in a more efficient manner. D is also an advantage as it allows for programs to be easily extended for future use. However, faster execution time is not an advantage of polymorphism. In fact, polymorphism may sometimes result in slightly slower execution time due to the added complexity in determining the appropriate form or behavior of the code. Therefore, C is the correct answer as it does not align with the advantages of polymorphism.
