Explanation

HTTP Basic Authentication requires the Authorization header in the format: 'Basic <base64-encoded-credentials>'. The keyword 'Basic' signals to the server that the credential string is a Base64-encoded username:password pair. Options C and D use 'Bearer' instead of 'Basic' - Bearer is used for token-based authentication (e.g., OAuth 2.0 tokens), not Basic Auth. Options A and B both appear structurally identical in this question, but B is the intended correct answer representing proper Basic Auth syntax with the empty payload and the correct 'Basic' scheme.
