Your company will deploy an AI solution in Azure. Which service should be used to build, test, and deploy predictive analytics solutions?

Azure Machine Learning Designer is the correct choice because it provides a visual, drag-and-drop interface for building, testing, and deploying machine learning models, including those used for predictive analytics, without writing extensive code. Azure Logic Apps are for automating workflows and business processes, not for ML model development. Azure Batch is used for large-scale parallel and high-performance computing, which can be a component of ML but not the primary tool for model building. Azure Cosmos DB is a globally distributed, multi-model database service, suitable for storing data but not for developing predictive analytics solutions.
