You Are Designing an Apache Beam Pipeline to Enrich Data

You are designing an Apache Beam pipeline to enrich data from Cloud Pub/Sub with static reference data from BigQuery. The reference data is small enough to fit in memory on a single worker. The pipeline should write enriched results to BigQuery for analysis. Which job type and transforms should this pipeline use?

A) Batch job, PubSubIO, side-inputs
B) Streaming job, PubSubIO, JdbcIO, side-outputs
C) Streaming job, PubSubIO, BigQueryIO, side-inputs
D) Streaming job, PubSubIO, BigQueryIO, side-outputs
