Which of these statements best describes the kinds of transforms a Cloud Dataﬂow pipeline can do?

Cloud Dataﬂow takes a query and runs information from the database through it to produce tables of data organized according to the requirements of the original query.
Cloud Dataﬂow relies on a large database to store and analyze data processing pipelines, performing transforms resulting in predictive analytics that can be leveraged to optimize business decisions.
Cloud Dataﬂow relies on training data to enable machine learning that can then read multiple streams of data and perform transforms that produce resulting output data.
Cloud Dataﬂow reads data in and can apply ﬁltering, grouping, comparing, joining, or aggregation

The correct answer is:

Cloud Dataﬂow reads data in and can apply ﬁltering, grouping, comparing, joining, or aggregation.
