The correct answer is A. <span>My favorite stores are Bloomingdale's and Macy's. My sister only shops at Nordstrom.
The names of the shops are Bloomingdale's, and Macy's - both of these shops have the apostrophe and then -s in their actual name, so these cannot be omitted. The third shop doesn't have an apostrophe and -s: its name is just Nordstrom. This is why the other options are incorrect.
