Fill in the blank with a suitable preposition.
Priya placed the sign ________ the door.
The prepositions ‘above’ and ’over’ mean higher than something. The difference is that ‘above’ is used when something is not directly in contact with the object on top, whereas we use ‘over’ when there is a contact between the two objects. In the given sentence both 'above' and 'over' can be used, since 'the sign' can be placed higher than the door or on top of it. Thus options A and B are correct. On the other hand ‘among’ is used when we are discussing something being amidst a group of elements or things. Whereas when we use ‘from’ it would mean that the sign is taken from the door, which is inappropriate. Thus options C and D are incorrect.
