The correct answer is C. RSS.

The correct answer is C. RSS.

Social-news sharing sites use RSS (Really Simple Syndication) to provide updates to users. RSS is a web feed format that allows users to access updates from their favorite websites or content sources in a standardized way. It delivers newly published content in a structured format that can be easily consumed by applications or users.

To find the answer to this question, you would need to understand the purpose and functionality of RSS and its usage in social-news sharing sites. By eliminating options A (HTML5), B (CSS3), and D (Flash), which are unrelated to the question, and recognizing that RSS is specifically designed for delivering updates, you can select C (RSS) as the correct answer.
