The second line of a frequency table shows the number of times each score appears in the data set. Counting the scores given, we have:
- 2 appears once
- 6 appears once
- 7 appears twice
- 1 appears once
- 8 appears once
- 5 appears once
- 4 appears once
Therefore, the correct second line of the frequency table is 7, 2, indicating that the score 7 appears 2 times in the data set. To calculate the percentage, we divide the frequency of each score by the total number of scores:
- 7 appears 2 times out of 8 total scores, which is 2/8 or 25%. 
So the answer is B.

Consider the Scores 2, 6, 7, 1, 7, 8, 5
