Answer:
The revision that most effectively corrects the dangling modifier in the sentence is the following one: To make a profit, the club must sell all the snacks.
Explanation:
A dangling modifier is a type of misplaced modifier. A dangling modifier is misplaced because it does not have anything to modify, the word/s it should be modifying or describing have been omitted from the sentence.
The original sentence does not include any noun phrase to which the infinitive clause can referred. The closest NP to the clause is "all the snacks" and it certainly can't modify said NP. Therefore, it is better to use an active voice sentence so that the infinitive clause can modifiy the doer of the action, "the club". They are the ones selling.
