The correct answer is A. Cross tab queries.
Cross tab queries are used to summarize data in a tabular format. They are best suited for analyzing data that can be grouped into categories. For example, you could use a cross tab query to summarize sales data by product category, region, or salesperson.
Parameter queries are used to run a query with different values each time it is run. This is useful when you want to be able to specify the values that you want to query on. For example, you could use a parameter query to find all of the customers who have placed an order in the past month.
Action queries are used to make changes to data in a database. This includes queries that delete, update, or insert data. Action queries should be used with caution, as they can make permanent changes to your data.
