b.The net may hang up to 60 ft below the work, with any mesh size
c.The net must be exactly 10 ft below the work, with 100-square-inch openings
d.The net only needs to cover half the fall zone

Correct: safety nets must be installed as close under the walking/working surface as practical and never more than 30 ft below it, and mesh openings must not exceed 36 square inches (nor 6 inches on a side). Hanging 60 ft below or unlimited mesh would let workers strike a lower level or pass through. A fixed 10 ft with 100-square-inch openings and 'half the fall zone' are both non-compliant; nets must cover the full potential fall area.
