What output results when calling a derived-class method that manipulates members not yet initialized, due to a constructor call in the base class?

Runtime error
Compiler error
Undefined behavior
Correct output

The correct answer is: Undefined behavior

Calling a derived-class method that manipulates members not yet initialized can lead to undefined behavior because the members have not been initialized yet. This can result in unpredictable output and potentially cause unexpected results in the program. It is important to ensure that all members are properly initialized before accessing or manipulating them in methods. Options A and B, runtime error and compiler error, respectively, may also occur in this scenario depending on the specific implementation. Option D, correct output, is not likely as the members are not yet initialized.
