In an abstract class, the methods that must be overridden in its subclasses are the Abstract methods.

Here's the step by step explanation:

1. An abstract class in object-oriented programming is a class that cannot be instantiated and is typically used as a base class for other classes.

2. Abstract methods are methods declared in an abstract class without any implementation. They are declared using the keyword 'abstract' and they do not have a body.

3. When a class extends an abstract class, it must provide an implementation for all the abstract methods declared in the abstract class, i.e., it must override all the abstract methods. If it doesn't, then the subclass itself must also be declared abstract.

4. Concrete methods, class methods, and static methods in an abstract class have their own implementation and do not need to be overridden necessarily. However, they can be overridden if needed.

So, the answer is Abstract methods.
