What is the minimum pulley diameter mentioned?

Explanation:
This question tests understanding why a minimum pulley diameter is specified in rope systems. When rope runs over a pulley, it bends around the wheel. If the pulley is too small, the bend is sharp, which increases bending stress on the rope, accelerates wear of the rope’s sheath, and can generate heat under load. This can shorten rope life and reduce performance or safety in use. The guidelines in the training material set a minimum diameter to prevent those problems, ensuring smoother operation and longer rope life. Among the given options, 12 mm is the smallest diameter that still satisfies that requirement, making it the correct choice. Larger diameters are acceptable, but anything smaller would exceed the recommended limit.
