I'd suggest you just go with whatever seems interesting to you
Absolutely agree. Adcoms aren't looking for a perfect applicant that has a particular job function. They look for someone that can express why you made those decisions in your career, where you demonstrated leadership, and why you think an MBA can help you reach your goals i.e. Entrepreneurship/Business Development.
Some applicants demonstrate leadership in areas other than career, e.g. outside activities, community involvement, hobbies, etc. It's really a matter of how you express who you are to the adcom. If you start thinking of what you think they want to see in you, you'll be missing the point. I've spoken to a lot of adcom that say they hate this! Focus on yourself, your interests, and your talent, and you're doing exactly what adcoms want.
