Direction: Choose the correct Preposition from the options given below to…

Certain English verbs combine with one fixed preposition to form a set idiomatic phrase (a collocation); the correct preposition in such phrases cannot be derived from the preposition's general meaning alone — it must be recognised as a memorised unit tied to the verb's specific, often figurative, sense of direction or contact.

Here, "arrive" is used in its figurative sense of reaching a conclusion after deliberation, rather than its literal sense of reaching a physical destination. English fixes the preposition for this figurative sense as "at" — the single point that the deliberation converges on. So the sentence reads: "The committee has not yet arrived at a final decision regarding the proposal."

Checking the remaining prepositions against their own standard collocational roles confirms none fits this figurative sense:

• "on" marks contact with a surface, a calendar reference, or a topic under discussion (e.g., "on the table", "on Monday", "a report on trade") — none of these match a point that deliberation converges on.

• "in" marks an enclosed space, a duration, or a state (e.g., "in the hall", "in June", "interested in painting") — again not the point-reached sense.

• "for" marks purpose, duration, or exchange (e.g., "waiting for a reply", "thankful for support", "traded for cash") — it signals aim or exchange, not the point actually reached.
