Answer #1

a. The user can write reviews of the items that they purchased. d. The user shall be able to create a wishlists, add item to and remove item from them.

-> the above two options are considered directly as usecases out of the remaining options.

reason : we know that , usecases define operations performed by an actor. Here the user is an actor who will use this online shopping system. So compare to all the other options these user options can be used for direct usecases and as given in other options system cannot be a perfect actor/usecase because it cannot work on it own someone has to operate it.
