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.
