Answer:
The correct answer is Option (C) [3. π ]
Step-by-step explanation:
In Maths interval is a set of real numbers which contains all real numbers lying between any two numbers of the set.
The intervals must be in brackets with comma. If the numbers are enclosed by normal bracket then the numbers not not include in the interval, if the numbers are enclosed by square bracket then the numbers are include.
So for example, [1, 9) if this the interval then 1 is included and 9 is not included.
In Options (A), (B), (D) all are enclosed with brackets and comma, but option (C) has not comma in the interval so it is not interval.
