We can use the following formula to calculate the H score:

H = 20 * log (mean score)

Using the data given in the table, we can calculate the mean scores for each newspaper:

Newspaper A: (50 + 50 + 53 + 58 + 59)/5 = 54 
Newspaper B: (59 + 60 + 63 + 65 + 67)/5 = 62.8 
Newspaper C: (45 + 48 + 51 + 54 + 55)/5 = 50.6 
Newspaper D: (62 + 64 + 68 + 70 + 72)/5 = 67.2

Then, we can plug these mean scores into the formula to calculate the H scores:

H for Newspaper A = 20 * log (54) = 14.95 
H for Newspaper B = 20 * log (62.8) = 16.17 
H for Newspaper C = 20 * log (50.6) = 13.18 
H for Newspaper D = 20 * log (67.2) = 17.03

Therefore, the newspaper with the lowest H score (i.e. the most readable) is Newspaper A, with an H score of 14.95. Thus, the answer is B.
