Which of the following relates to searching for news, reports, and multimedia?

The correct choice pertains to the functionality of searching for news, reports, and multimedia content. NSE, which stands for News Search Engine, is specifically designed for retrieving relevant news articles and multimedia materials based on user queries. This tool enables users to access a vast array of information swiftly, making it an essential feature for those seeking timely updates and comprehensive insights into various topics or sectors.

In contrast, the other options do not specifically cater to the search for news and multimedia. HYM, CBMU, and USGA serve different purposes or functions that may not directly relate to the task of finding news and multimedia, thus making them less relevant in the context of this question.
