Which API is used to locate a user's position in a web browser?

• A. Canvas API
• B. Web Storage API
• C. HTML Geolocation API
• D. Drag and Drop API

Answer: (C)

The HTML Geolocation API is used to locate a user’s position in a web browser. It lets a page ask for permission to determine the user’s geographic location and, if granted, provides coordinates (latitude and longitude), along with accuracy and a timestamp. Typical usage uses navigator.geolocation.getCurrentPosition to fetch the current location or watchPosition to receive updates over time. Location data depends on device sensors or network information and usually requires a secure context (HTTPS) and user consent; if permission is denied, an error occurs. This API enables location-aware features like maps, nearby searches, or weather updates. The other APIs handle different tasks: the Canvas API is for drawing graphics, the Web Storage API stores data locally in the browser, and the Drag and Drop API handles dragging and dropping elements.
