B.
Primary is a 2-node RAC DB system and Standby is a 2-node RAC DB system.
C.

D.
Primary is a 2-node RAC DB system and Standby is a 1-node RAC DB system.
E.
Primary is a Bare Metal DB system and Standby is a 1-node RAC DB system.
B and C
When you use the Console or the API to enable Data Guard for an Exadata database compute node database:
The standby database is a physical standby.
The versions of peer databases (primary and standby) are identical.
You are limited to one standby database for each primary database.
in Option D the secondary is a 1 node RAC which should not work.
Oracle has a support for one node RAC

Note that one rac node is kwon in oracle, also creating DG by OCI Console requires to have the same shape.
