Drinking Roost, a children’s health drink, must be a good habit. This

I vote for C. it took me a couple of seconds to decide between C and D, while A,B,E are clearly wrong.

My reason is that D has a target for upper class, and the Roost works. If we know that the Roost is for everyone from the stem, then option D is correct.
C is the right choice because this option told us that the limitation of the data, which weakened the conclusion

I opted C. As the claim states that it must be good for health. And the option C casts doubt upon the sample space irrespective of the income strata i.e. in general the concerns are raised.

Chose D. Please help me eliminate C. I tel you why C is wrong. C states that 'The claim was made only by small percentage of the children’s population who drank Roost in the country.'
Now I understood from C that - 'small percentage of c's population who drank Roost' implying that out of the total population of children, only a small % drinks Roost and they were fresh. So, does not weaken.
May be you understood that - out of the c's population that drinks Roost, only a small % was fresh. Then it might weaken.

But why should not I go by my understanding and eliminate C?

It is C. Because, the claim is made by young cricketers not by cricketers from all segments including adult group.

It is not D. Because, nowhere in the argument it is saying that the claim is made by the upper strata of people.

Could someone please help me with option D as I am still unable to understand the true gist behind that option and why it is incorrect. If the claim was made by children, who kept good health in spite of health drinks, then we cannot conclude that drinking Roost must be a good habit. If the children are already healthy to begin with, then the conclusion falls apart. My reasoning behind option C was that even if the claim was made by a small % of the people, the conclusion can still hold that drinking roost must be a good habit. Can someone please shed a light on this? Would greatly appreciate it!

I don't agree that the argument has a sampling error.

"Interviews conducted with young cricketers who drank one cup of Roost each before and after the match, confirmed that the players were feeling much fresher than those who did not take the health drink" --> This implies a one off event, but the conclusion says that it must be a good habit.

Hence the main flaw is that the evidence really is irrelevant. A one of event cannot justify an habit [if you take a painkiller to cure pain before an ailment, does it make taking painkillers a good habit ? No]. However, under the circumstances, the best option really is C. Though sampling is not really a flaw here.

Could you explain difference between choice C and D

We need to find the flaw in the argument : the conclusion not actually indicates that it is applicable for the entire population who consumes the drink but rather focuses only on effects young cricketers.
Nothing is stated about effects on others who consume the drink. It may be the case that the drink has some negative effects on those who are not actually interviewed- including their experiences may change the conclusion. We need to take the holistic view and then only can conclude about the efficiency of the drink.

Choice C states " The claim was made only by small percentage of the children’s population who drank Roost in the country" and points out the limitation of the argument properly.

On the other hand choice D states "The claim was mainly made by children who belonged to upper strata of people, who kept good health in spite of health drinks"

It does not indicate who drank the health drink-if it is consumed by only upper class children the representative group is only them, not the others.
Additionally the wording in the last part is also ambiguous: in spite of health drinks children kept good health ! So is it the case that the drink was not beneficial at all and they needed to take something else to improve efficiency?

Choice C is much clearer and points to the flaw directly. Hence C is correct.

VeritasKarishma can you please help in eliminating D? I think it's a good contender to be a correct answer.

Ignore the question. It is not GMAT-like.
