Answer:
actually I'm thinking of the wrong definition
it would be dvd and tv and gas and car, because you can connect the dvd player to the tv to enhance its features, and a car needs gas to run so maybe A and D
not this maybe
it seems to me it would be oranges and apples
as they are different but equally the same, both fruits and healthily for you
and Maybe hats and gloves, their for different parts of the body but used for the same function keep worth (or just used to avoid blisters) is my guess
