The Derived class inherits from the Baseclass. In the constructor of the Derived class, it calls the base class constructor using base (ii) , where ii is passed from the Derived constructor. The base class constructor initializes the variable I with the value passed to it and then prints “Base”.
After initializing the base class, control returns to the derived class constructor, which then prints “Derived”.
Therefore, when you run this program, the output will be: Base Derived.

The constructor of the derived class implicitly calls the constructor of the base class.

Actually, the base class object is created in the program that's why the base class method is invoked. If you create derived class object with derived class reference then only we can call both class methods.

Base keyword is used to call the base class constructor.

Why E ? Can the constructor be inherited ?

Can anybody tell me how it's giving the option E Answer?
Because when we use the parameterise type of constructor we need to pass the default constructor.

The base keyword used in derived class gives the call to its base class.

Constructor call it self when we create object of it.
