No issue.
A default constructor with dynamic allocation of objects is created a default constructor accepts no parameters. So the constructors that are created will have same characteristics.

What if the constructor assigns random values to the member variables of the instance of the class ?

What is the differnce b/w option A and C ?
Please clarify the solution.

I do not think compiler will assign the content to both object and I tried to VS2010 and show that objects has the different content
BaseClass s1,s2;// = new Drived();
s1 = new BaseClass();
s2 = new BaseClass();
if (s1 == s2)
{
Console.WriteLine("contents of both objects are same");
}
BaseClass s1,s2;// = new Drived();
s1 = new BaseClass();
s2 = new BaseClass();
if (s1 == s2)
{
Console.WriteLine("contents of both objects are same");
}

In terms of memory allocated to s1 and s2 they are equal i.e.
All objects created from a class will occupy equal number of bytes in memory.

I am agree with Indrapal. I have also tried it and it shows that objects has the different content.

@Indrapal.
s1 and s2 contains the address that where the content is stored.
So s1 and s2 are stored at diff memory locations so obviously if block won't execute.
@Paurush.
Exactly same means including addresses of the objects,
But its not true as I explained above,
So the answer is C only.

Yuk, sneaky question :)
I think a lot of C# programmers will assume that 'the contents of s1' mean the object pointed to it. I did. Have to say that it's more clear if you rewrite in C++ :D

Slightly sneaky indeed. It shouldn't say 'Contents of..exactly the same'. It would be more correct to say 'The characteristics of the two objects will be the same'.
That covers off the scenario mentioned above where member data is being initialised to random or otherwise variant values.
