The test scores at Millbrook High School are normally distributed, and the 60th percentile is equal to a score of 70. Quantity A: The 30th percentile score Quantity B: 35.

I think the answer is A because the data are more concentrated on the mean in normal distribution. But the solution says the answer is D. Could you tell me which one is correct? If I am wrong, please explain why.
