I don't think I can tell you the right answer since I don't know you personally. But I can tell you how I answer it; which is I think of my best traits that apply to the position I'm interviewing for. You should follow the same thought process prior to the interview; what do you bring to the table for this job. Are you experienced in the field? Do you have high productivity compared to other people you've worked with? Are you really enthusiastic about the work? If it's a team based environment, do you have experience working in or even teams in this field? That's how you answer that question.
