Question

Final Answer : D, Explanation :  The pregnancy test that detects hCG is most reliable when conducted approximately 1 week following a missed period. Ovulation occurs approximately 14 days before a woman's expected period, so conducting the test immediately after having intercourse or even 3 days after may not provide an accurate result. Conducting the test 5 days before her expected period may also not be accurate as the level of hCG may not be high enough to detect yet. Therefore, conducting the test approximately 1 week following a missed period is the best choice.
