Question 7 options:
a Set only implements Collection, a List only implements Iterable.
a Set has no duplicate entries, a List may have duplicate entries.

a Set is a superinterface of List, hence there is no difference.
A)a Set only implements Collection, a List only implements Iterable.
B)a Set has no duplicate entries, a List may have duplicate entries.
C)a Set cannot be implemented with a backing array, but a List is always implemented that way.
D)a Set is a superinterface of List, hence there is no difference.
Explanation / Answer
Fundamental difference between List and Set in Java is allowing duplicate elements. List in Java allows duplicates while Set doesn't allow any duplicate. If you insert duplicate in Set it will replace the older value. Any implementation of Set in Java will only contains unique elements.
