Which of the following is NOT a common type of cargo block?

Explanation:
Cargo blocks are pulley assemblies used in lifting and rigging, designed with a housing that holds a rotating sheave and attachment points for rigging. The common designs you’ll see include shapes like diamond or oval, which fit standard mounting and rope routing patterns, and roller bearing blocks, which use rollers to reduce friction and handle heavier loads more smoothly. A cylindrical form wouldn’t provide the stable enclosure and side plates needed to secure the axle and bearings or to keep the rope properly aligned. It would also be awkward to attach and support in typical rigging setups, so cylindrical blocks aren’t a standard type.
