frequency: 8/ 0/ 10/ 2
b. internal: 56-63/ 63-70/ 70-77/ 77-84/91-98
frequency: 1/7/0/5/2
c. internal: 50-70/ 70-80/ 80-85/85-90/90-100
frequency: 8/0/6/4/2
d. internal: 60-75/ 75-90/ 90-105

The first step is to find the minimum and the maximum values in the data. Then you will be able to choose probable intervals for the histogram. Next you can find the number of data values that fall in each of the intervals that are to be trialed for suitability. You will find that one of the choices is a suitable frequency table for the histogram.
