Explanation

Magnetic tape is the optimal choice for high-capacity, cost-effective offsite backup. Tape cartridges (e.g., LTO tape) can hold terabytes of data per cartridge at a very low cost-per-gigabyte compared to other media, they are portable and easy to transport offsite, and they are self-contained - requiring no assistance to store once written. DVDs (B) have very limited capacity (4.7–8.5 GB) and would require an impractical number of discs for large backups. Floppy disks (C) are effectively obsolete with negligible capacity. SSDs (D) are expensive per gigabyte, making them cost-ineffective for large-scale backup compared to tape. Tape has been the industry standard for archival and offsite backup for decades for exactly these reasons.
