To answer this question, we need to understand the concept of interfaces in programming.
An interface is a collection of abstract methods that can be implemented by any class. It defines a contract that specifies what methods a class must implement if it wants to be considered as implementing that particular interface.
Now, coming back to the question, the statement "All interfaces must contain IDrivable" is false. This is because an interface can define any methods, and it is not necessary for an interface to contain the method "IDrivable".
Therefore, the correct answer is B) False.
