A Correct answer
Explanation

The correct phrase is 'boils down to,' meaning to reduce to or be essentially about something. When a complex situation is explained in its simplest form, it 'boils down to' the core issue. The other particles don't form correct phrasal verbs with 'boils' in this context of simplification.
