When running the Linux prerequisites script for NDB, the -t argument is a required parameter that specifies the timeout interval. This argument defines the maximum time (in seconds) the script will wait for certain operations (e.g., connectivity checks, package installations) to complete before timing out. This is critical during the preinstallation phase to ensure the environment is properly configured and responsive, avoiding indefinite hangs. Other options are not associated with -t:
* A. Operating System type: This is not a typical argument for the prerequisites script.
* C. NDB server IP: This would be specified separately (e.g., via -s or a similar flag).
* D. Database engine: This is irrelevant to the prerequisites script, which focuses on system setup.
Thus, the verified answer is B, aligning with the script's purpose of managing execution timeouts.
