C# Variable MCQs

Question 11: What will be the output of the following program?

public static void Main()
{
    var str = null;
	Console.Write(str);
}

Answer: C

You cannot assign a null to an implicitly typed variable because the C# compiler sets the type of a var variable based on the value, and if the value is null, then it cannot decide the type. So, it gives a compile-time error.
