Which statement best describes the HTML5 File API?

• A. It allows you to validate input types on the server side.
• B. It enables client-side access to local files for reading and uploading content securely.
• C. It provides a database to store user data.
• D. It is used for styling file input controls.

Answer: (B)

The HTML5 File API lets a web page access files on the user’s computer from within the browser in a controlled, secure way. It exposes File and FileList objects that represent files the user selects (through an input element or drag-and-drop) and a FileReader to read those files’ contents as text, data URLs, or binary data. This enables you to read or preview files on the client side and then upload them to a server if needed, without sending anything to the server first. The browser keeps file access sandboxed and requires explicit user action, so you get a safe, client-side workflow for reading and uploading content.
