A mobile application developer has been asked to write an application that will work even when there is no connectivity. When input data is to be saved, the application must determine whether it should be written to the server or to a cache. How should the application developer do this?

• A.Use the Worklight API call WL.Framework.addEventListener to register callbacks when WL.Events.WORKLIGHT_IS_CONNECTED andWL.Events.WORKLIGHT_IS_DISCONNECTED are fired by the Worklight framework.
• B.Call WL.Server.isConnected() before every call to the Worklight server, and write to the cache if it returns false.
• C.Use the JavaScript API call Document.addEventListener to register callbacks when WL.Events.WORKLIGHT_IS_CONNECTED andWL.Events.WORKLIGHT_IS_DISCONNECTED are fired by the Worklight framework.
• D.Use the Worklight API call WL.Server.setConnectivity() to register a function to be called whenever the application goes offline or comesback online.
