A) high standard deviation in MTBF
B) low standard deviation in MTBF
C) low Cost to Repair
D) Repairs carry little non-monetary consequences.
E) The system never fails.
Preventive Maintenance Program
A schedule of planned maintenance actions aimed at preventing breakdowns and failures of equipment before they occur.
Cost Effective
Cost-effective refers to an action that provides the best possible outcome for the least amount of money, maximizing the benefits relative to its costs.

Final Answer :
B
Explanation :
If the cost to actually perform preventive maintenance is very expensive, it is likely that the maintenance will be performed less frequently, resulting in a more consistent and predictable Mean Time Between Failures (MTBF). This would lead to a lower standard deviation in MTBF, making option B the best choice. The other options are not directly related to the cost of performing preventive maintenance.
