A state park environment is best suited for Marcello's workplace priorities.
Answer: Option C
Explanation:
A state park would be the best place for Marcello to work as it would allow him to be active and work outdoors. A state park would require Marcello to move from one place to another and always be on the look-out for something or the other.
A retail store, an office cubical and a public library would not allow Marcello to work outdoors and stay active. Working in an office cubicle or a public library would require Marcello to sit for long hours and work without requiring active body movements.
