The correct option is B To track and trace missing children
On June 29, Suresh Prabhu, the Union Minister of Commerce & Industry and Civil Aviation, launched a mobile application “ReUnite” in New Delhi to track and trace missing and abandoned children in India. The app is multiuser where parents and citizens can upload pictures of children, and provide detailed description like name, birth mark, address, report to the police station, search and identify missing kids. The photographs will not be saved in the mobile phone’s physical memory. Amazon Rekognition, web facial recognition service, is being used to identify missing kids. The app is available for both Android and iOS.
