What is a potential risk of a recursive function that is not properly terminated with a base case?
- AIt will cause a compile-time error.
- BIt will always return an incorrect value.

What is the fundamental conceptual difference between "pass-by-value" and "pass-by-reference" for function parameters in C?
- APass-by-value is used for primitive types, while pass-by-reference is used for composite types.
- BIn pass-by-value, a function works with a copy of the argument, whereas in pass-by-reference, it works with the original variable via its memory address.
- CPass-by-value allows a function to modify the original variable, while pass-by- reference protects the original variable from modification.
- DThe choice between pass-by-value and pass-by-reference is made automatically by the compiler based on the variable's type.
