You are installing two hard disk drives on a computer. Which of the following possible combinations can be used? Each correct answer represents a complete solution. Choose all that apply.

An IDE primary controller typically supports two devices (master and slave), so installing a second hard disk drive on the primary controller alongside a first is a valid configuration, ensuring proper jumper settings for master/slave.

Distributing the two hard disk drives across separate IDE controllers, such as placing the first on the primary controller and the second on the secondary controller, is a common and valid installation method that often improves performance.

This choice is incomplete and does not describe a full, actionable installation combination.

While installing both hard disk drives on the primary IDE controller is a valid configuration (as master/slave), the question asks for all possible combinations, and B provides another distinct valid method.
