Suggested Answer: C 🗳️
The MyBase keyword behaves like an object variable referring to the base class of the current instance of a class.MyBase is commonly used to access base class members that are overridden or shadowed in a derived class.

Answer B seems more appropriate. The question states how should you access the "Truck class" implementation of the brake() method. MyBase.brake() would access Vehicle.brake().

I agree with this, it states the "Truck class" implementation, calling MyBase.brake or base.Brake would call the Vehicle class' implementation of brake.

nvm, read the question wrong. in overriden methods called in the derived class that overrode the method this.break() calls the implementation of the derived class base.break() calls the implementations of the base class

C. this.Brake() is the best answer. -------------------------------- class Vehicle { protected string Brake() { return "Breaking..."; } } class Truck : Vehicle { public string DoTruckWork() { return this.Brake(); } } static void DoTruck() { Truck truck = new(); Console.WriteLine(truck.DoTruckWork()); } --------------------------------

"...How should you call the Truck class implementation of the brake () method?" As far as I understood it you need to call the .Break() over a new instance of Truck. Truck does not have a declaration of Break to be called.
