A Correct answer
Explanation

Drive duplexing uses two controllers to write data simultaneously to separate drives, providing both redundancy and improved performance over simple disk mirroring which typically uses a single controller. The dual-controller architecture allows concurrent writes and better throughput. Option C describes basic mirroring without the dual-controller benefit, D describes RAID 5 striping with parity, and B is too vague.
