Which file formats does Watson Discovery support?

Watson Discovery is designed to handle a variety of file formats to extract insights from diverse data sources. The correct response highlights that it supports PDF files, Word documents, HTML, and JSON formats. These formats are particularly common in business applications and web content, making Watson Discovery versatile for analyzing documents that organizations typically encounter.

PDF and Word documents are prevalent in corporate environments, used for reports, contracts, and other textual information. HTML files represent web content, which can be useful for gathering data from websites. JSON, a lightweight data interchange format, is commonly used for APIs and data storage, making it essential for integrating with modern web applications and services.

Other options provided do not encompass the breadth of formats supported by Watson Discovery. CSV and XML, while common in data processing, are not the only formats in which Watson Discovery excels. Likewise, the inclusion of just JPEG and PNG as image formats does not leverage Watson Discovery’s full capabilities, which extend significantly beyond handling only image files. Therefore, option B is accurate and reflects Watson Discovery's ability to analyze a wide range of document types to provide valuable insights.
