Which is most likely part of a healthy heart and lung system?

A. daily exercise
B. carbohydrate-rich diet
C. maintaining a high body mass index
D. diet low in vegetables and lean proteins

Answer 1

The answer is A.

This is because you do not want to diet low in vegetable because that would be bad for your body. So D is crossed out. You don’t want to have a high body mass index which means weight.. so you don’t want to gain a lot of weight. So C. Is out. You definitely do not want a rich carbohydrates diet because that’s bad for you. So A is the answer.
