  • D. [plum, banana, carrot, apple]
  • E. [plum, apple, carrot, banana]
  • F. [banana, plum, carrot, apple]
  • G. Compilation fails


B is correct.

Note

ArrayList elements are automatically inserted in the order of entry.

They are not automatically sorted.

ArrayLists use zero-based indexes.

The last add() inserts a new element and shifts the remaining elements back.
