This is little confusing. But I will go with C

Kudos drives a person to better himself every single time. So Pls give it generously
Wont give up till i hit a 700+

I would also go with B, and my reasons are also in line with what Skientist has written above, the only difference I neglected C was because it in no ways connects - "Adequate Prenatal care with low birth weight" as it is done in final conclusion.

Although I took long time to solve this question, a little over 3 minutes. seems to be a 700+

whats the source, if you know?

Premise 1 - Medical Researcher: As expected, records covering the last four years of ten major hospitals indicate that babies born prematurely were more likely to have low birth weights and to suffer from health problems than were babies not born prematurely.
Premise 2 - These records also indicate that Mothers who had received adequate prenatal care were less likely to have low birth weight than were Mothers who had received inadequate prenatal care.

Conclusion - Adequate prenatal care, therefore, significantly decreases the risk of low birth weight babies

Low birth weight has been shown as a function of two variables i.e. premature delivery and inadequate pre-natal care.

A)The hospital records indicate that many babies that are born with normal birth weights are born to mothers who had inadequate prenatal care. (“Many” creates ambiguity, eliminate)
B)Mothers giving birth prematurely are routinely classified by hospitals as having received inadequate prenatal care when the record of that care is not available. (This is our answer as it shows that the recoed may not be reliable, thus weakening the conclusion)
C)The hospital records indicate that low birth weight babies were routinely classified as having been born prematurely. (It is not linked to prenatal care, thus does not weaken the conclusion)
D)Some babies not born prematurely, whose mothers received adequate prenatal care, have low birth weights. (“Some” creates ambiguity, eliminate)
E)Women who receive adequate prenatal care are less likely to give birth prematurely than are women who do not receive adequate prenatal care. (This strengthen the conclusion. It proves that inadequate prenatal care leads to premature birth which in turn leads to low birth weights)
