The output of code is ?

1. class test

2. {

3. public void print()

4. {

5. Console.WriteLine("Csharp:");

6. }

11. {

12. test t;

13. t.print();

14. Console.ReadLine();

15. }

16. }

• Code runs successfully prints nothing

• Code runs and prints “Csharp”

• None of the mentioned

• Syntax error as t is unassigned variable which is never used

What is output for the following set of code?
