Your logic is perfect giddi, then why doubt???
Thanks vivek. When I was in high school my grammat teacher use to mention that ENGLISH IS A MONKEY LANGUAGE. There are more exceptions than rules.
I find that more than half of the times LOGIC does not work. I am still learning the GMATical rules.
I must comment that your questions and participation/discussion here has helped me (and definitely other GMAT clubbers) a lot and encouraged me to solve more SCs from the 1000's collection.
