I believe the second answer choice explanation should say you can't specify generic type on the left hand side in this manner (it currently says right hand side)

The right hand side has a problem. It is missing a dot i.e. it should be:
PlaceHolder<String, String> ph2 = PlaceHolder.<String>getDuplicateHolder("b");
instead of
PlaceHolder<String, String> ph2 = PlaceHolder<String>getDuplicateHolder("b");

That is why the explanation says Right hand side.
