Thank you Kenneth, Interesting one :-)
I have selected the wrong answer, thinking either you change the script or query option, the change is compulsory. And later i read the question again, so came to know the query option change wouldn't matter, but just the script should not be modified.
(In general, if a person parse the code then it will show error/s, so he has to take some careful steps to read the script and then change the query option to meet the script. If A has written the script and B is going to execute and B is not aware of the modified batch terminator and if B is trying to execute it via his machine with default settings, then A and B are going to have some pleasant conversation :-) )
The first and the hardest SQL statement I have wrote- "select * from customers" - and I was happy and felt smart.
