Explicitly means we have to delete manually.

No.
Because compiler does not provide any default constructor when we provided explicitly.

Please clarify my doubt. Class is declared as virtual then how the class contain destructor?

Destructor is invisibility in your program and it's call automatically. Because every constructor program using inside destructor.

In C++ there is no automatic garbage collection.

But if object goes out of scope, destructor is called automatically. Then why we need to call it explicitly?

Destructor can be virtual because whenever the object goes in out of the scope then we have to delete it explicitly.

Virtual functions provide run time polymorphism as the function to be executed is decided at run-time.
