A) Functions serve as abstraction mechanisms by eliminating redundant or repetitive code. By creating a function, we can take a block of code that might be used in several places in a program and condense it down to a single function that can be called whenever that code is needed. This not only simplifies the program but also reduces the chance of errors due to code duplication.
C) Functions can also serve as a way to hide complicated processes. For example, a program might have a complex algorithm for calculating the path of a particle in a physics simulation. By hiding this algorithm inside a function, the rest of the program doesn't need to know about the details of how the particle's path is calculated. This makes the program simpler and easier to use, because the user only needs to provide inputs and can trust that the function will provide the correct output.
