In belt drives, which statement correctly compares V-belts and timing belts in terms of slip, alignment sensitivity, and maintenance?

• A. V-belts rely on friction and can slip under overload; timing belts have teeth that prevent slip and maintain precise timing; V-belts tolerate minor misalignment but require tensioning, while timing belts require accurate center distance and periodic replacement.
• B. V-belts rely on teeth to prevent slip; timing belts rely on friction and slip easily.
• C. V-belts require no tensioning; timing belts require constant lubrication.
• D. V-belts are maintenance-free; timing belts never need replacement.

Answer: (B)
