Fill in the blank with a suitable preposition.
You knock the nails _______ a hammer first, before painting the wall. [Basic]
The preposition ‘with’ is used to denote a tool used for performing something. In the given context ‘a hammer’ is the tool that aids in removing the nails. Therefore option D is correct. On the other hand ‘for’ is used to show the reason or purpose behind something. The nails are not removed for the sake of the hammer. Hence option B is incorrect. Whereas ‘within’ and ‘to’ are inappropriate in the given context since they denote a place and a destination respectively. Both of these are irrelevant since the sentence doesn't refer to a place. So options A and C are incorrect.
