Consider the following JavaScript statements. Which of the following, when placed after these two statements (where / ADD STATEMENT HERE appears), would complete the task of swapping the values stored in num1 and num2? That is the original contents of num1 would be assigned to num2, and the original contents of num2 would be assigned to num1. temp = num1; num1 = num2; // ADD STATEMENT HERE O temp = num 1: O temp = num2; O num1 - num2: O num2 = num1: num2 = temp:
