Explanation

The preposition "OF" is mostly used either in the possession sense, like "he is a part OF that team", or "the painting OF Ahmed" and to relate two parts of a sentence with one another, for example, "a story OF passion", "the city OF Karachi", "Pakistani Heritage" or "Second of January" The preposition "TO" is mostly used as an extension of a verb or action, like "I will be going TO the park", "I want TO play" or "I hope TO see you again" The preposition "ON" is used as an indication of place, or of time, like "I am ON the plane", " I will play that song ON the guitar" (guitar is a place in this sense), "What's on TV" or "It on Monday"(in the time sense) The preposition "as" is mostly used to refer to the purpose or role of a noun, like "I work AS a waiter", or "The pile of books served AS a laptop stand". As can also be used to tell two things happening at the same time, for e.g "He arrived AS I left", or as a replacement of because for e.g "He was jealous AS (because) I came first" As the sentence is talking about an action that will happen, the best-suited preposition will then have to be 'to' so option B is correct
