I would say A based on this Data access behavior using the new Policy Rules vSAN Stretched Clusters have traditionally written a copy of data to each site using a Mirroring Failure Tolerance Method. These were full writes to each site, with reads being handled locally using the Site Affinity feature. Write operations are dependent on VM Storage Policy rules in a vSAN 6.6 Stretched Cluster. Dual Site Mirroring/Primary Failures To Tolerate behavior When a Primary Failures to Tolerate rule is equal to 1, writes will continue to be written in a mirrored fashion across sites. When a Primary Failures to Tolerate rule is equal to 0, writes will only occur in the site that is specified in the Affinity rule. Reads continue to occur from the site a VM resides on. https://core.vmware.com/resource/vsan-stretched-cluster-guide#sec7306-sub5
