Explanation

Dropping celldisks is a destructive administrative operation, so it requires either the CELLADMIN account (the privileged admin account on Exadata storage cells) or a custom user explicitly granted privileges on celldisk objects - both can invoke CELLCLI, either interactively per cell (F, B) or distributed across all cells simultaneously via DCLI (A). Options C and E are wrong because CELLMONITOR is a read-only monitoring account with no write or destructive privileges - it cannot drop anything. Option D is wrong because, while it references an administrator-created user (like B), the tool or method described in the truncated option is invalid for this operation (likely referencing an incorrect approach such as DCLI without proper privilege mapping). The key insight is that DCLI wraps CELLCLI to run the same command across multiple storage servers in parallel, making it ideal for rack-wide operations like this reconfiguration.

Memory tip: Think "CELLADMIN = action, CELLMONITOR = monitor." For tools, CELLCLI runs on one cell; DCLI runs on all cells - "D" in DCLI stands for Distributed.
