Final Answer :
C
Explanation :
The method add() is used to add elements to an ArrayList. It places the element at the end of the list by default, but it can also insert new elements at a specified position. The method set() is used to replace an existing element at a specified position. The method put() is not a valid method for ArrayLists. The method place() is not a valid method for ArrayLists as well.
