B: Scores below the top 14% and above the bottom 57%
C: Scores below the top 43% and above the bottom 24%
D: Scores below the top 76% and above the bottom 8%

  57 to 63

Step-by-step explanation:

A suitable probability tool can tell you the limits.

  8% of scores will be below 56.95 ≈ 57

  76% of scores will be above 63.24 ≈ 63

Scores between 57 and 63 will get a D grade.

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
