d. a and b
e. b and c

e. b and c

Explanation:

We can say that a person who diet without physical exercise will lose a few pounds, but this in addition to being unhealthy will make it difficult to maintain the "new" weight of the person.

Dual diet and exercise is the only healthy way to lose weight, and it is the only way to maintain weight for a long time. People on the diet alone will faint, but soon their body will accumulate more calories and fats that will not be burned by physical exercise. The result is that this person will be much more likely to return to their previous weight and get stuck in one type of weight cycling.
