Answer 2

Explanation:

When a person sitting in a chair, his center of mass will be at the middle of chair legs. But as he tries to stand up, he has to move his center of mass to his foots. Therefore, we bend little forward while standing up from straight chair, to keep balance. This is because we have to balance our centre of gravity.
