Answer: (B)

In a maintenance context, "service life" refers to the expected performance period of equipment before it requires replacement. This encompasses not just the physical durability of the equipment but also its operational effectiveness during that time. Understanding the service life is crucial for maintenance planning, as it allows organizations to schedule replacement or upgrades and manage resources effectively. Essentially, it defines how long the equipment is expected to function reliably under normal conditions, which helps in determining maintenance strategies and budgeting.
