The slice() method is used to extract a portion of an array and returns a new array. In this case, Melissa wants to extract the spring months which are February, March, and April, and they are located in the indexes 2, 3, and 4 respectively. Therefore, the slice method should be used with the start index being 2 and the end index being 5 (exclusive) which will return a new array containing the three spring months. Option B will remove the spring months from the original array, which may not be what Melissa wants to do. Option C and D will not include all the spring months.
