Correct Response: A. One of the best ways to check the authenticity of an image is to use a reverse image search to see where else the image shows up on the Internet. If the image was misappropriated, this is a quick way to find the original. B is incorrect because the WHOIS information reveals the ownership of the website, but not of the content it contains. C is incorrect because the named photographer could have posted the photo in several places even if it was not their original work. D is incorrect because even if available, this type of camera metadata provides only indirect support for the identity of the image owner.
