Which of the following HTTP status codes indicates a successful response?

• A. 404
• B. 500
• C. 200
• D. 302

Answer: (C)

The HTTP status code 200 indicates a successful response. When a client sends a request to a server and receives a 200 status code, it means that the request was successfully processed, and the server has returned the requested resource as expected. This status code is part of the 2xx class of responses, which specifically indicates successful interactions between the client and the server.

In contrast, the other codes represent different states of request handling. For example, a 404 status code means that the requested resource could not be found on the server, indicating a client-side error. The 500 status code signifies a server error, meaning that something has gone wrong on the server while processing the request. The 302 status code is used for redirection, indicating that the resource requested has been temporarily moved to a different URI, which also does not denote a successful retrieval of the requested resource. Therefore, among the options provided, 200 is unequivocally the status code representing a successful response.
