Please look at the figure carefully. The question is written, and one has to match the two columns 1 and 2 given under "choices and explanation". Please tell me if I am really wrong, i.e. would you match C with both 1 and 3, or just 3. (my answer and the right answer is shown at the right hand side)

Thanks!

Yes you are correct!

it is a known bug in VMC answers. If you search their forums as well ,some 2 years old questions perhaps, you'll find this.

The friction is static and just opposes the external force. Hence the friction force is just $4.5N$, and body will remain at rest.

@SaurabhRaje The point is not the marks in VMC. Also it's same for everyone. Just see you were right. –  Mr.ØØ7 May 25 '13 at 17:10
