Preposition 'between' means 'in or into the space which separates at least two places, people or objects.' So, Option A is the correct answer as the sentence seeks to draw out a comparison for two things. Options B, C and D cannot be used as 'on' means 'on the top of' or 'on the surface of,' 'out of' is generally used to show what something is made from, and 'of' is used to indicate reference or amount generally. Hence, these options they would render the sentence meaningless.
