Answer:
Mountains and Businesses
Explanation:
“Mountain Climbers” wouldn’t make sense because the section from the article doesn’t discuss anything about climbing mountains.
“Famous Mountain Ranges” also wouldn’t fit because the section doesn’t describe or list any famous mountain ranges.
“Mountain Wildlife” wouldn’t fit either because wildlife in the mountains is not included in the section.
The section talks about how mountains “provide the best environment and resources for economic activities” which fits in with “Mountains and Businesses” which is why that option would be the best fit.
