Explanation:

Step1: Understand stem - and - leaf plot

In a stem - and - leaf plot, the stem represents the tens digit and the leaf represents the units digit. For example, with key 2|5 = 25, for the row 2|5, the data entry is 25; for row 3|4, the data entry is 34.

Step2: List data entries

From the stem - and - leaf plot:
Stem 2: 25
Stem 3: 34
Stem 4: 41, 42, 42, 45, 46, 46, 48
Stem 5: 50, 51, 52, 53, 53, 54, 54, 54, 55, 56, 56, 58, 59
Stem 6: 68, 68, 68
Stem 7: 73, 78, 78
Stem 8: 85

Step3: Find maximum

The maximum value among these data entries is 85.

Step4: Check options

Option D has all the correct data entries as listed above.

Answer:

D. 25, 34, 41, 42, 42, 45, 46, 46, 48, 50, 51, 52, 53, 53, 54, 54, 54, 55, 56, 56, 58, 59, 68, 68, 68, 73, 78, 78, 85
