Nonambiguous, overloaded methods must have the same _____. a. types of parameters b. number of parameters c. parameter names d. name

To address the question, we need to understand the concept behind method overloading in programming, particularly in object-oriented languages like Java or C#.

Method overloading allows a class to have more than one method with the same name but different parameters. For nonambiguous overloaded methods, the core condition is that they must differ in either the number or type of parameters to avoid confusion in invocation.

Analyzing the Options:

1. a. types of parameters: This could be true, but overloaded methods could also differ by the number of parameters instead of their types.
2. b. number of parameters: This is a valid condition; methods can be overloaded by having a different number of parameters.
3. c. parameter names: This is not relevant for overloading; parameter names do not affect method signature.
4. d. name: All overloaded methods must have the same name, which is the defining aspect of overloading.

Conclusion:

The correct answer is that nonambiguous, overloaded methods must have the same name and can differ in types or number of parameters. Given the options and the critical rule of method overloading, the best choice here is d. name.

Final Answer:

d. name
