Suggested answer: B

Explanation:

Dual storage controller architectures have more than one storage controllers to provide redundancy in case of failure of a single controller. This ensures that if one controller fails, the other controller can take over the workload and keep the data accessible. This also provides a high level of reliability, as the system can continue to operate even if one controller fails.
