The correct option is Azure Portal.

Using the Azure Portal is the simplest approach for a single one off proof of concept because it gives an interactive graphical interface that lets the team create a NoSQL database quickly without writing infrastructure code.

The portal provides guided forms, sensible defaults, and quickstart workflows so the team can focus on testing data and queries rather than building and validating deployment scripts.

Bicep script is an infrastructure as code tool intended for repeatable, automated deployments and pipeline integration. It requires authoring templates and using tooling which is unnecessary overhead for a one time manual proof of concept unless you specifically need the deployment described as code.

ARM template deployment is a declarative, repeatable deployment method that also requires template development and validation. It is better suited for consistent, version controlled deployments rather than a single quick creation for a proof of concept.

Google Cloud Console is the management interface for Google Cloud Platform and not for Azure. It cannot be used to provision Azure NoSQL databases so it is not applicable to this scenario.
