Point P = new Point();
In this case, there is two things have been created.
1- Pointer named P in the Stack.
2- Object in the heap.
Here Object has no name, However, when you create an object and give it a name you give the pointer that name not the object itself. So that objects are nameless as the answer says.

This is dubious at least. Objects can be named and created on the stack if they are value-types. Only instances of reference types are always nameless. Value-types are objects but they are not reference types, because they ultimately inherit from system object (which is an object). Inheritance is a relation, so value-types is a object.

new sample();
When the above statement is executed then it satisfies all the rules of object creation and also it's a nameless object

It is completely wrong to say that object are always nameless,
For one time use we make object anonymous but not always.

In the sense that objects are reference counted I suppose 'E' is correct but it's a sightly odd way of putting it. By that I mean that in this example:
wibble a = new wibble();
wibble b = new wibble();
We have two nameless objects on the heap and two variables 'a' and 'b' that point them. Generally an irrelevant distinction but not if we add:
wibble c=a;
Now we have a third variable but still only two objects.
wibble a = new wibble();
wibble b = new wibble();

Option E applies only because all the other options are incorrect. Objects can be named or nameless.

Object can be nameless or named. Objects need not compulsory a nameless object, if we don't declare object name in the expression then nameless object gets created automatically or else a named object.

For example:
class sample
{
}
class test
{
//creating object for sample
sample ob=new sample();
}
Then tell me what is obj, its name of the class only right?
class sample
{
}
class test
{
//creating object for sample
sample ob=new sample();
}
Then tell me what is obj, its name of the class only right?

String str1="Some Value";
String str2="Some Value";
Now compare both: str1.Equals(str2) // Here Both the Objects have name str1 and str2, But
str1.Equals("Some Value"); // Here the second string is anonymous object or nameless object.
My view is Object can be nameless but not always.
String str2="Some Value";
Now compare both: str1.Equals(str2) // Here Both the Objects have name str1 and str2, But
str1.Equals("Some Value"); // Here the second string is anonymous object or nameless object.
My view is Object can be nameless but not always.
