Explanation:
VMware vCenter Update Manager Administration Guide vCenter Update Manager 4.0, page 11

Updates you specify can be applied to operating systems, as well as applications on scanned ESX/ESXi hosts, virtual machines, and virtual appliances. With Update Manager, you can:
1. Scan for compliance and apply updates for guests, appliances, and hosts.
2. Directly upgrade hosts [B above], virtual machine hardware, VMware Tools, and virtual appliances [C above].
3. Update third-party software on hosts.

Update Manager can scan and remediate (update) powered on, suspended, and powered off virtual machines, and templates [E above], in addition to scanning and remediating hosts. If the upgrade or patching fails, you can revert the virtual machines back to their prior condition without losing data. Update Manager can scan and remediate powered on, VMware Studio registered, Red Hat, Ubuntu, SUSE, and CentOS Linux virtual appliances [Not Solaris so A is incorrect] . You can deploy Update Manager in a secured network without Internet access. In such a case, you can use the VMware vCenter Update Manager Download Service to download patch metadata and patch binaries.
