Considering where it ﬁts in the GCP, Cloud Datastore is good for:

Highly structured databases or transactional databases.
Organizations with non-relational data that want to reduce their operations burden with an enterprise-grade database.
Relational database management at scale that requires high availability and HTAP.
Flat data and databases with lots of read-write actions.

The correct answer is:

Organizations with non-relational data that want to reduce their operations burden with an enterprise-grade database.
