Consider the following table structure:CREATE TABLE Products ( Product...
The correct answer is option 'B'. The SQL statement will calculate the average unit price of products with units in stock.

Explanation:
- The SQL statement begins with the keyword SELECT, which is used to retrieve data from a database.
- The AVG() function is used to calculate the average value of a specified column. In this case, it is used to calculate the average unit price.
- The column specified in the AVG() function is UnitPrice, which represents the unit price of each product.
- The FROM keyword is used to specify the table from which the data should be retrieved. In this case, it is the Products table.
- Since there is no WHERE clause in the SQL statement, all rows in the Products table will be considered for calculating the average unit price.
- However, since the AVG() function only considers non-null values, any rows with a null value in the UnitPrice column will not be included in the calculation.
- Therefore, the average unit price will only be calculated for the products with non-null values in the UnitPrice column.
- The result of the SQL statement will be the average unit price of all products that have units in stock.
- This means that the average unit price will be calculated only for the rows where the value in the UnitsInStock column is not null.
- Option 'B' correctly identifies that the SQL statement will calculate the average unit price of products with units in stock.
