The correct answer is A. A cross tab query.
A cross tab query is a type of query that summarizes information in a grid, organized by regions and months. It is used to analyze data and find trends.
A cross tab query is created by selecting the fields that you want to summarize and then clicking the “Cross Tab” button on the “Design” tab. The query will then be created and displayed in a grid.
The rows of the grid will represent the regions and the columns will represent the months. The cells in the grid will contain the summary of the data for each region and month.
For example, if you have a table of sales data, you could create a cross tab query to summarize the sales by region and month. The query would then display a grid with the rows representing the regions and the columns representing the months. The cells in the grid would contain the total sales for each region and month.
A cross tab query is a powerful tool that can be used to analyze data and find trends. It is a simple and easy-to-use tool that can be used by anyone.
