Answer: (C)

Preventive maintenance is considered crucial for engines primarily because it helps in avoiding costly repairs and ensures reliability. By regularly inspecting, servicing, and maintaining engine components, potential issues can be identified and addressed before they develop into significant problems that require extensive repairs. This proactive approach not only saves money in the long run but also enhances the engine's performance and longevity.

Regular maintenance activities, such as oil changes, filter replacements, and inspections of belts and hoses, are integral to ensuring the engine operates smoothly and efficiently. This not only extends the life of the vehicle but also helps maintain optimal fuel efficiency, leading to fewer unexpected breakdowns and delays. The reliability gained from consistent preventive maintenance is essential for safe and efficient vehicle operation.
