Solution
The correct option is B 2
On the first fold, we will get a half-circle. On the second fold, we will get a quarter circle. Then open the folded sheet. The two creased lines intersect at a point. This point is the centre of the circular sheet.
So, in total, we will have to fold the sheet twice.
