Which of the following is correct set notation?
(1,2,3)
1,2,3
{1,2,3}
None of the above
Answer: The correct option is
(C) {1, 2, 3}.
Step-by-step explanation: We are given to select the correct set notation from the following options :
Option (A) : The given notation is (1, 2, 3).
Here, the elements are enclosed within first brackets, which is not used to write a set.
So, this option is NOT correct.
Option (B) : The given notation is 1, 2, 3.
Here, the elements are not enclosed within any brackets. And, the elements of a set is always written within curly brackets.
So, this option is NOT correct.
Option (A) : The given notation is {1, 2, 3}.
Here, the elements are enclosed within curly brackets, separated by comma. Since this method is used while writing a set, so, this option is CORRECT.
Thus, (C) is the correct option.
