Options
- AUse Cloud Data Fusion and Wrangler to normalize the data, and set up a recurring job.
- BUse Dataflow SQL to create a job that normalizes the data, and that after the first run of the job, schedule the pipeline to execute recurrently.
- CCreate a Spark job and submit it to Dataproc Serverless.
- DUse BigQuery and GoogleSQL to normalize the data, and schedule recurring queries in BigQuery.

Explanation
Option A is correct because Cloud Data Fusion's Wrangler is a visual, no-code data preparation interface specifically designed for data cleansing and normalization tasks - like standardizing phone formats and country codes - without writing any code. Once you build the transformation pipeline visually, Data Fusion natively supports scheduling it as a recurring job, satisfying all three requirements: BigQuery integration, normalization, and recurrence with no coding.
Option B (Dataflow SQL) is wrong because writing SQL is coding, and scheduling a recurring Dataflow pipeline requires additional orchestration setup, making it neither "no coding" nor "quick."
Option C (Spark on Dataproc Serverless) is wrong because Spark jobs require writing code in Python, Scala, or Java - directly violating the "no coding" constraint.
Option D (BigQuery scheduled queries) is a tempting distractor since BigQuery does support scheduled queries and connects directly to your data, but writing GoogleSQL is still coding, and the question explicitly rules that out.
Memory tip: When a GCP exam question says "no coding" + "data normalization" + "recurring job," think Data Fusion + Wrangler - it's Google's purpose-built, code-free ETL tool with a visual wrangler for exactly these kinds of format-standardization tasks.
