C Correct answer
Explanation

X is a method header because it includes modifiers (public, final), return type (String), method name (getDetails), parameters (File file, String key), and throws clause. Y is a method signature because it only includes the method name and parameter types without modifiers or return type.

AI explanation

A method header is the full declaration line: access modifiers, return type, method name, parameter list, and any throws clause — exactly what X shows (public final String getDetails(final File file, final String key) throws IOException). A method signature is narrower: just the method name plus the ordered list of parameter types — exactly what Y shows (getDetails(File, String)), with no modifiers, return type, or exceptions. So X is the header and Y is the signature, making the third option correct. The other options mislabel one or both, or wrongly claim they're the same kind of construct.
