AI Explanation

To answer this question, we need to understand how elements are stored and retrieved from a Vector.

A Vector is an ordered collection of objects, similar to an array. Elements in a Vector are stored with an index, starting from 0.

In this case, when the method removeElement("Evers") is called, the string "Evers" is removed from the Vector. This means that the original index positions of the remaining elements may change.

Let's go through each option to determine which one retrieves the string "Chance":

Option A) get(1) - This option retrieves the element at index 1 in the Vector. Since the string "Evers" was removed, the string "Chance" would now be at index 1.

Option B) get(2) - This option retrieves the element at index 2 in the Vector. However, after removing "Evers", "Chance" would now be at index 1, not index 2.

Option C) get("Chance") - This option is not a valid method for retrieving elements from a Vector. The get() method in a Vector requires an integer index, not a string.

Option D) None of the above - This option is incorrect because option A (get(1)) is the correct answer.

Therefore, the correct answer is A) get(1). This option retrieves the string "Chance" from the Vector.
