Chemical pregnancy tests that measure the presence of human chorionic gonadtropin (HCG) sometimes exhibit a false negative, indicating that the woman is not pregnant when in fact she is; the tests can also give a false positive response, indicating that the woman is pregnant when she actually is not. Consumers should seek the pregnancy test with the lowest proportion of false negative results in order to most accurately detect pregnancy with an at-home test.
The conclusion to the left is most strongly supported by which of the following, if true?
A. Some ultrasounds can detect pregnancy as early as one week into the gestation.
B. Early symptoms of a pregnancy can include nausea, increased hunger, and disturbed sleep patterns.
C. Prenatal medical supervision should begin as soon after conception as possible.
D. All at-home pregnancy tests have the same rate of inconclusive test results.
E. All at-home pregnancy tests produce the same proportion of false positive result

IMO E.
If all other at home tests have the same proportion of false positive result, then, in order to maximise the chances of test correctness, the test with lowest proportion of false negative results should be used.
