B,E Correct answer
Explanation

An overriding method can declare narrower or fewer checked exceptions than the overridden method, or none at all. It can also increase visibility (e.g., from protected to public). Thus, throwing FileNotFoundException (a subclass of IOException) or keeping the original signature are both valid.
