How should I list these two jobs on my resume?

Dates employed at Job A: December 2015 - present

Dates employed at Job B: January 2016 - May 2017

Both are part time jobs. I currently work another job (we'll call it Job C) with dates employed October 2017 - present. I have been listing my work experience in this order:

Job C

Job A

Job B

Because I still currently work at Job A and Job C. However, Job B is most relevant to positions I am applying for. Would it be more correct to list jobs chronologically by start date? Like this:

Job C

Job B

Job A

Thanks for any advice.
