Answer :
The advice that I will give to my friend is that it is not a good plan because it does not include healthy eating and exercise that is option D is correct.
In order to keep the body healthy, there should be a proper intake of healthy food and also along with healthy food exercise is also necessary. There should be a proper diet of how many calories should be taken to keep the body in shape and in balance form. Using of supplements and other intoxicating substances to build body is not a good method as it can have a negative impact on the health in longer run. As my friend wants to use supplements and avoid exercise to increase the muscle gain, I would suggest her not to do so as it is not a good method of increasing muscle gain. This can hamper her growth in a negative manner.
