Official USCG Answer & Rule Citation

Correct Answer: Option B — obtain the flexibility required for easy handling and reduces skin effect losses

Stranding large marine electrical conductors increases physical flexibility for installation and mitigates skin effect losses, where high-frequency alternating current tends to concentrate near the conductor's outer surface, complying with IEEE 45.
