Which of the following has a rated capacity of 25,000 lbs?

The correct answer is "None of the above" because none of the items listed have a rated capacity of 25,000 lbs.

The 5/8-inch screw pin clevis typically has a rated capacity of 8,800 lbs, which is insufficient for the requirement. The 10,000 lbs apex fitting is rated for, as the name implies, 10,000 lbs, which also does not meet the 25,000 lbs requirement. Similarly, the 10,000 lbs sling leg is again only rated for 10,000 lbs. Therefore, none of the listed options fulfill the criterion of having a rated capacity of 25,000 lbs, making "None of the above" the correct answer.
