Fill in the blank with a suitable preposition.
Would you like a glass _______ apple juice?
The preposition ‘of’ is used to denote belonging or relation. In the given sentence the glass is filled with apple juice, thus 'of' establishes the connection between the glass and apple juice. Therefore option B is correct. On the other hand, ‘for’ cannot be used because when we use ‘for’ it would mean that the apple juice needs a glass, which is inappropriate here. Thus option A is incorrect. Whereas ‘from’ denotes the starting point while ‘with’ denotes company. Both of these are irrelevant in the given context because 'apple juice' is neither a place from which something originates nor an object that accompanies the glass. Hence options C and D are incorrect.
