Cute 😀. Let's just pretend this isn't flamebait, and give a reply anyway. DOS is a layer on top of BIOS, Windows 3.1 is a layer on top of DOS. Like the BIOS provides common interfaces (more or less APIs) used by DOS to handle many things, Windows 3.1 uses DOS and its API to handle many things. However, Windows 3.1 also provides its own drivers, and its own API, for programs running under Windows 3.1, allowing them to do many things impossible under plain DOS. So in that respect, neither DOS nor Windows 3.1 are 'true' OSes, but both have common features found in OSes in general. When running Windows 3.1, BIOS + DOS + Windows together make the OS.
