Fill in the blank with a suitable preposition.
The group won _______ the help of its fans. [Basic]
The preposition ‘with’ is used to denote the tool used to perform something. In the given context ‘the fan’s help’ is the tool that aids in the victory of the group. Therefore option B is correct. ‘For’ is used to show the purpose behind something. The group didn’t win so that they can help the fans. Hence option A is incorrect. Similarly ‘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 C and D are incorrect.
