The correct answer is "Using super()".

Constructor chaining from a base class in object-oriented programming languages like Java is achieved using the "super()" keyword. This keyword is used to call the constructor of the parent class. This is necessary when you want to access methods or variables of the parent class which has been overridden in the child class.

Here is a step by step guide on how to implement constructor chaining from a base class:

1. Define the base class with its constructor. The constructor should initialize the variables of the base class.

2. Define the derived class which extends the base class.

3. In the derived class, use the "super()" keyword in the constructor to call the constructor of the base class.

4. Now, when you create an object of the derived class, it will first call the constructor of the base class (due to the "super()" keyword), then it will call the constructor of the derived class. This is constructor chaining from the base class.

Remember, the call to "super()" must be the first statement in the derived class constructor.
