Answer 1

memory drawing pin we will use to display the exam time table on the school notice board because it is very small in size and it can be eaten in to the notice board very easily and it is very helpful to US and it is very safe to use

Answer 2

We will use (b) for pinning up the time table to the notice board because the surface of the board is somewhat stiff. So much pressure is needed to be applied on the surface and we know that narrower bases are used to apply great pressure . So the pushpin shown in Fig. (b) is used.
