### Solution:

Given

Width of the continuous classes is 5

Frequency table is starting from 10

Total interval in a frequency distribution table is 5

Lower class-limit of the highest class?

Frequency distribution

10-15

15-20

20-25

25-30

30-35

According to above data

Highest class is 30-35 and lower class-limit of the highest class is 30, so b is correct.
