Explanation

ResourceBundle.getBundle() expects a base name without the .properties extension, but the code passes "Captions.properties" as the base name. Java then searches for files like Captions.properties_en.properties and ultimately Captions.properties.properties - none of which exist - so it throws a MissingResourceException rather than falling back to the actual Captions.properties file.

Why the distractors fail:

• D (UserName) - looks correct since Captions.properties has that key, but the wrong base name means Java never resolves to it as a fallback
• E (User name EN) - would require resolving Captions_en.properties, which only happens with base name "Captions", not "Captions.properties"
• A / C - both US-related bundles (Captions_US / Captions_en_US) are similarly unreachable for the same reason, and neither even contains the "user" key

Memory tip: Think of the base name as a class name, not a file name - just as you write MyClass, not MyClass.java, you write "Captions", not "Captions.properties". Including the extension is a common trap that breaks bundle resolution entirely.
