Which scenario would most likely lead to a higher level of physical fitness among people who live in a city

Hello. This question is incomplete. The complete question would be:

"which scenario would most likely lead to a higher level of physical fitness among people who live in a city

More people live near a fitness center.  More people walk to school or work.  More people carpool with neighbors.  More people have access to fruits and vegetables."

More people walk to school or work.

Explanation:

"More people carpool with neighbors" and "More people have access to fruits and vegetables." they do not influence the physical fitness of people in the same city at all. In addition, the "More people live near a fitness center" option could influence, but it does not, because not everyone would do the gym, nor would they do it every day.

However, the option "More people go to school or work" is an option that influences people in the same city to improve their physical fitness, as work and school are something they cannot avoid, and walking would be an exercise that would improve their physical fitness.
