The correct answer is "for" because the preposition "for" is used to indicate purpose or allocation, and in this context it correctly shows that the funds are being allocated with the purpose of developing rural infrastructure. The phrase "allocate for" is the standard and grammatically correct collocation in English when indicating what something will be used towards. Other prepositions like "to," "towards," or "in" would either be grammatically incorrect with "allocate" or would create awkward phrasing that doesn't properly convey the intended meaning of purpose. This is a matter of proper preposition usage, where certain verbs require specific prepositions to maintain grammatical correctness.
