D Correct answer
Explanation

The correct phrase is 'by means of' when indicating the method or instrument used to achieve something. This is a fixed idiomatic expression meaning 'through the use of'. Options A and B incorrectly reverse the preposition order, and option C contains a typo ('menas' instead of 'means').
