a.25 percent of the weight of the cargo
b.At least 50 percent of the weight of the cargo being secured
c.100 percent of the weight of the cargo
d.There is no numeric requirement

The combined working load limit of all tiedowns must equal at least half the weight of the article being secured. Twenty-five percent is below the standard, requiring 100 percent overstates the rule, and the requirement is clearly numeric.
