The outstanding Invoice file should be stared on a Pardon Access Storage Device if A. invoice data entry is on-line. B. payment recording is done in a batch rode C. inquires concerning payable are to be answered on-line D. last record points to the first record E. None of the above

The correct answer is: A. invoice data entry is on-line.

A random access storage device (RASD) is a storage device that can access any data on the device without having to read all the data before it. This is in contrast to a sequential access storage device (SASD), which can only access data in a linear order.

RASDs are typically used for applications that require fast access to data, such as online transaction processing (OLTP) and online analytical processing (OLAP).

In the case of an outstanding invoice file, it is important to be able to access the data quickly so that invoices can be paid promptly. If the invoice data entry is on-line, then a RASD is the best choice for storing the data.

Options B, C, and D are not correct because they do not require fast access to data. Option E is not correct because it is not a valid option.
