A- wrong answer ( it is true though fo migration from Solaris 10 => 11.
Answer should be E, since according to documentation:

Link Names in Upgraded Systems
In systems where this Oracle Solaris release is freshly installed, datalinks are automatically named net0 through netN-1, where N represents the total number of network devices.
The case is not true if you upgrade from Oracle Solaris 11 Express. On such upgraded systems, the datalinks retain their names prior to the upgrade. These names would either be the default hardware-based names, or customized names that the administrator assigned to the datalinks before the upgrade. Further, on these upgraded systems, new network devices that are subsequently added also retain the default hardware-based names rather than receive neutral names. This behavior for upgraded systems ensures that no neutral names that are assigned by the OS become mixed with other hardware-based names or customize names assigned by the administrator before the upgrade.
