The question asks which statement will produce the minimum of all standard prices from the Product_V table.
Option 1: 'SELECT Standard_Price FROM Product_V WHERE Standard_Price = min;' This is invalid SQL because 'min' is not defined as a scalar or function in this context; you cannot compare a column to an undefined value. The syntax will fail before returning any result.
Option 2: 'SELECT Standard_Price FROM min(Product_V);' This is not valid SQL syntax. You cannot call 'min' as if it were a table or a function wrapping the entire table in this way. The correct usage would involve an aggregate, not a direct function-style call on the table name.
Option 3: 'SELECT MIN(Standard_Price) FROM Product_V WHERE Standard_Price = min(Standard_Price);' Here, there are multiple problems. MIN(Standard_Price) is an aggregate that must be used in a SELECT list or HAVING clause, not in a WHERE clause with a comparison to a scalar produced by MIN(Standard_Price) in the same query. Moreover, mixing an aggregate in a WHERE without a subquery or HAVING is not allowed, so this will raise an error.
Option 4: 'SELECT MIN(Standard_Price) FROM Product_V;' This statement correctly uses the aggregate MIN on the column Standard_Price to produce the smallest value across all rows in Product_V, returning a single scalar result. It adheres to SQL aggregation rules and will yield the minimum price value as intended.
In summary, only the fourth option adheres to proper SQL syntax for retrieving the minimum of all standard prices, while the first three misuse aggregation or syntax in ways that prevent correct execution.
