Ans:
we can override the parent class method under its child
class only when the parent class declared the method as
virtual

ex:
class Parent
{
public virtual void Test()
}
now thar virtual method of the parent class can be override
the child class using override modifier

ex:

class child:Parent
{
public override void Test()
{
Console.WriteLine("hi this is derived class") ;
}
}

but it is only optional for the child classs to override the
virtual method of its parent class
