🧠 Explanation:
The preposition “with” fits the sentence “A young police officer was charged with the tasks of transporting the prisoners,” indicating responsibility assignment. Prepositions clarify relationships between actions and objects, ensuring grammatical accuracy. “With” is apt for assigning duties, reflecting natural English usage in professional contexts. Understanding prepositions enhances clarity in communication, particularly in legal or administrative settings. The choice of “with” conveys the officer’s role vividly, making the sentence precise. This linguistic precision is vital in formal writing, ensuring clear expression of responsibilities in scenarios like policing or management.
