The correct answer is “D” !
You need 3 disks for parity + 1 for data = 4.
More information could be found in ONTAP Cluster Administration, Student Guide.

A 7
Upgrading from the RAID-DP type (min 6) adds spare disk as additional parity diska and adjust the RAID size accordingly

Answer is A
Vitaly is correct. The confusion here is migrate vs CREATE.
If you are migrating from DP then the minimum is 6…here is documentation
— https://library.netapp.com/ecm/ecm_download_file/ECMLP2496263
HOWEVER if you are CREATING (new/from scratch) the GUI will show that the MINIMUM is 7
The question did NOT mention converting from DP to TEC. so answer is A

Answer A is correct.
As Andy said, the GUI shows minimum is 7 as showed in the link below

RAID4 -> Minimum 3 disks (2 data, 1 parity)
RAID-DP -> Minimum 5 disks (3 data, 2 parity)
RAID-TEC -> Minimum 7 disks (4 data, 3 parity)
