The answer will be b.
Explanation:
the .set() method performs a replacement for any element in an ArrayList you specify(the number in the parentheses) and the value you wish to replace it with ("Beth").
In the example, they are specifying the 1st element in the ArrayList. Important to remember that in programming, ArrayList a zero-indexed.
// indices 0 1. 2. 3. 4. 5. 6
aList = [Wei, Marila, Anna, Neal, Rachel, Jack, Aneesh]
The element that the example is replacing is Marila because Marila is the element at index 1.
