Which of the following statements about hiking is true? a. it can be done in both rural as well as urban settings. b. it can be both an aerobic as well as an anaerobic exercise. c. it lets you explore the outdoors at your own pace. d. all of the above.

ANSWER:
 "C. It lets you explore the outdoors at your own pace."

WHY NOT A?
You cannot go hiking in an urban area. If you're not familiar what an urban area is, here's the definition: a human settlement with high populations. 9 times out of 10, you're not going hiking by skyscrapers and heavy traffic.

WHY NOT B?
You cannot live without oxygen. This answer would've been correct if it wouldn't have said you can exercise without oxygen (anaerobic exercise).

WHY NOT D?
Well... This one is obvious. If A and B is eliminated, then the answer cannot be "All of the above".

It can be peer pressure, also when they’re going through a lot of stuff at home
