Inner duct inside a conduit creates multiple internal pathways, which increases conduit use by letting you route more cables within the same outer conduit. This setup makes future cable additions easier and less disruptive because you can pull new cables into unused inner ducts without installing new conduits. It also helps with organization and protection during pulls, reducing the chance of damage and simplifying upgrades later. The other options describe costs or downsides (higher material costs, reel memory/microbends, longer install time), which aren’t advantages.
