While setting up the thresholds for tablespace space usage metrics for one of your tablespaces， you define the critical threshold as 60% and warning threshold as 75%. What would be the result of this setting？（）

• A、It would result in an error because the warning threshold cannot be more than the critical threshold.
• B、The warning threshold is ignored and alerts would be generated when space usage exceeds the critical threshold.
• C、The critical threshold is ignored and alerts would be generated when space usage exceeds the warning threshold.
• D、Both threshold values are used and alerts are generated when space usage exceeds the respective threshold values.
