The keyboard shortcut for Internet Recovery that initiates the installation of the latest available version of macOS is Option+Command+R. This combination tells the Mac to connect to the internet and download the most current macOS version that is compatible with your hardware. By using this shortcut upon startup, the Mac will make an online connection to Apple’s servers, allowing it to download and install the latest OS or the one that is compatible with the Mac model.

The other options serve different purposes: Shift+Command+R is used to install the macOS version that originally came with your Mac or the closest version still available. Option+Shift+Command+R does not correspond to a recognized Internet Recovery function. Control+Option+R is not a valid shortcut for starting an Internet Recovery either and does not correspond to any known recovery option. Thus, among the choices given, Option+Command+R correctly facilitates accessing the latest version of macOS during Internet Recovery.
