The correct answer is: A. may
A derived class may override attributes of a parent class. This means that the derived class can provide its own implementation for an attribute that is also defined in the parent class. This can be useful if the derived class needs to change the behavior of the attribute or if it needs to provide a different implementation for the attribute for different types of objects.
For example, consider the following code:
“`class Animal {
public string name;
public void Speak() {
Console.WriteLine(“I am an animal”);
}
}
class Dog : Animal {
public override string name {
get { return “Spot”; }
}
public override void Speak() {
Console.WriteLine(“Woof!”);
}
}
“`
In this code, the Dog class overrides the name and Speak attributes of the Animal class. This means that a Dog object will have a name property that is set to “Spot” and a Speak method that prints “Woof!”.
Overriding attributes can be a powerful tool, but it is important to use it carefully. If you override an attribute in a derived class, you should make sure that your implementation is compatible with the implementation in the parent class. Otherwise, you may end up with unexpected results.
