D. The question HA for US and APAC. Any answer which mentions Europe must be wrong. That eliminates A and C. HA requires > 1 cluster, so B must be wrong, leaving D. D shows 2 clusters in US and 2 in APAC.

Looks like D to me - it's the only one with 2 US and 2 Asia regions. Also https://cloud.google.com/bigtable/docs/replication-settings#regional-failover
