In C, we have "other health problems"

>Scope of the argument is about lung function only and hence C is out of scope. Also, we are not talking abut general people but specific category.

For others

D is an alternative solution and not assumption. Also "stop smoking" is out of scope

B and C compare diets and lung function with comparable diets ..which is not the argument deals with.

okers with proper diet and non.smokers with
C-as above


For E-negation test is succesful...If chemicals prevent vitamins to enter blood stream, lung function wont improve and conclusion will fall apart
