A set of CSV files contains sales records. All the CSV files have the same data schema.Each CSV file contains the sales record for a particular month and has the filename sales.csv. Each file in stored in a folder that indicates the month and year when the data was recorded. The folders are in an Azure blob container for which a datastore has been defined in an Azure Machine Learning workspace. The folders are organized in a parent folder named sales to create the following hierarchical structure: At the end of each month, a new folder with that month's sales file is added to the sales folder.You plan to use the sales data to train a machine learning model based on the following requirements:You must define a dataset that loads all of the sales data to date into a structure that can be easily converted to a dataframe.You must be able to create experiments that use only data that was created before a specific previous month, ignoring any data that was added after that month.You must register the minimum number of datasets possible.You need to register the sales data as a dataset in Azure Machine Learning service workspace.What should you do?

Create a tabular dataset that references the datastore and specifies the path 'sales/*/sales.csv', register the dataset with the name sales_dataset and a tag named month indicating the month and year it was registered, and use this dataset for all experiments.

Create a tabular dataset that references the datastore and explicitly specifies each 'sales/mm-yyyy/sales.csv' file every month. Register the dataset with the name sales_dataset each month, replacing the existing dataset and specifying a tag named month indicating the month and year it was registered. Use this dataset for all experiments.
