Final answer:
Rigging components must have a 10 to-1 safety factor.
Step-by-step explanation:
In rigging, components must have a safety factor to ensure that they can handle the expected load without failure. The safety factor represents the ratio between the breaking strength of a component and the maximum load it will be subjected to. By having a higher safety factor, there is a greater margin of safety and reduced risk of failure.
In this case, the question asks for the ratio of the safety factor. The possible answers are A) 2, B) 5, C) 10, and D) 15. The correct answer is C) 10, because rigging components typically have a safety factor of 10 to 1, meaning the breaking strength is 10 times greater than the maximum load.
