To create an image using vSphere Lifecycle Manager, the mandatory requirement is to specify the ESXi version. An image is a collection of software components that define the desired state of hosts in a cluster. An image must include at least one ESXi version component, which determines the base hypervisor software for the hosts. Optionally, an image can also include other components, such as vendor add-ons, firmware and drivers add-ons, or custom components. The other options are not correct. A component is a generic term for any software element that can be included in an image, but it is not a specific type of component. A firmwareand drivers add-on is an optional component that provides firmware and drivers updates for hardware devices on the hosts. A vendor add-on is an optional component that provides vendor-specific software for the hosts. References: About Images; Create an Image
