List<String> list = new ArrayList<>();
list.add("Apple");
list.add("Banana");
list.add(1, "Cherry");
list.remove("Banana");

["Apple", "Cherry"]["Apple", "Cherry", "Banana"]["Apple", "Banana", "Cherry"]["Cherry", "Apple"]

Answer and explanation

Correct answer

A. ["Apple", "Cherry"]

Why

The list initially contains "Apple" and "Banana". The operation list.add(1, "Cherry") inserts "Cherry" at index 1, resulting in ["Apple", "Cherry", "Banana"]. Then, list.remove("Banana") removes the element "Banana" by value, leaving ["Apple", "Cherry"].
