Which three feed types can be used for importing data into dynamic campaigns in Studio? (select three)

Studio supports Google Spreadsheets, CSV files, and Google Merchant Center feeds for importing dynamic data. These formats are widely used and provide flexible ways to manage and update campaign content. Google Spreadsheets allow for collaborative editing and easy integration with other Google services. CSV (Comma Separated Values) is a universal, lightweight format for tabular data. Google Merchant Center feeds are specifically designed for product data, making them ideal for e-commerce campaigns. XLS (Microsoft Excel Spreadsheet) files are not directly supported for dynamic data feeds in Studio; data from XLS files would typically need to be converted to CSV or Google Sheets first.
