Correct Answer: Option A

Explanation

The Set data type in JavaScript is a constructor that creates a new set object, which is a collection of unique values.
The add method is used to add a new value to the set object.
The has method is used to determine whether the set object includes the specified value.
In this case, two values are added to the set object using the add method.
The has method is called on the set object, with the value 2 as the argument.
Since the set object includes the value 2, the has method will return true.
