AContinue operations; this is within acceptable limits
BReduce the load to 50% of rated capacity
CRemove the rope from service immediately
DApply extra lubrication and recheck in one week

✓ Correct answer: C. Remove the rope from service immediately ASME B30.5 requires removal from service if the wire rope diameter has decreased more than 1/64 inch from nominal for ropes up to 3/4 inch diameter. A 1/64-inch reduction on a 3/4-inch rope is exactly at the removal threshold.
