Answer 1

The correct option is A (a) and (c)

Class intervals like 1 - 10, 11 - 20,.... are called inclusive class intervals because both upper and lower limit belong to that particular class interval

Limits and boundaries are different in inclusive class intervals,
for example :-

Limits	Boundries
1-10	0.5 - 10.5
11-20	10.5 - 20.5

Class intervals like 1 - 10, 10 - 20,.... are called exclusive class intervals because only lower limit belongs to that particular class interval.

Limits and boundaries are the same in exclusive class intervals,
for example:-

Limits	Boundries
0-10	0 - 10
10-20	10 - 20
