Hint: A preposition is a word used to link nouns, pronouns, or phrases to other words within a sentence. They act to connect the people, objects, time and locations of a sentence. Prepositions are usually short words, and they are normally placed directly in front of nouns.

Complete step by step answer:
Option A) Of – is an incorrect answer because we use ‘of’ to show a connection or belonging and ‘Of’ is used to indicate possession, relation, substance, cause or about. As it does not fit the meaning of the sentence correctly, thus, this is an incorrect answer.
Option B) To – is the correct answer because ‘to’ is used to indicate when indicating that there is movement from one place to another or ‘To’ is used to indicate direction, purpose, limit, attachment, comparing. The given sentence indicates a comparison. Thus, this is an incorrect answer.
Option C) With – is an incorrect answer because ‘with’ is used to indicate means, possession, contents, relationship, for and against. It does not fit the meaning of the sentence. Thus, this is an incorrect answer.
Option D) For – is an incorrect answer because ‘for’ is used to indicate a space of time, use of something, to show who is intended to have or use something. It is incorrect as it does not bring out the meaning of the sentence. Thus, this is an incorrect answer.

So, the correct answer is “Option B”-What’s more important to you. Independence or security?

Note:
Every preposition has their own purpose in the sentence. Thus, other prepositions i.e. for, with and of does not go well in the blank or bring out the incorrect meaning of the sentence. Thus, option B is the most appropriate answer as compared to other options.
