Refer to the Exhibit. The list of devices attached to vmhba1 will be the basis for configuring a VMware Virtual SAN using Manual Mode.
Based on the exhibit, which two combinations of devices should be used to create Disk Group(s)? (Choose two.)
A. One Disk Group with one Flash Drive and three HDDs
B. Two Disk Groups with one Flash Drive and two HDDs each C. One Disk Group with one Flash Drive and four HDDs

Correct answer is B,C, I think.
I answered my own question.

For a hybrid cluster, consider using at least 10 percent of flash cache to consumed capacity ratio (not including replicas such as mirrors).
– System has 4 HDD capacity 279.40 GB and 2 flash 93.16 GB
If choose C: one Flash Drive (93.16 GB) less than 10 percent of four HDDs (279.40 x 4 = 1117.6 GB)
So A and B is correct.
