Answer 1

The correct option is C (a) and (d)

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

In '1 - 10', 1 and 10 both belong to '1- 10' class interval.

The Inclusive class interval is the same as the discrete class interval.

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

In '1 - 10', only 1 belong to '1- 10' class interval.

The exclusive class interval is the same as the continuous class interval.
