The correct choice is (d) Natural rivers used for navigation rarely gets silted up posing no cost issues

The best I can explain: Natural rivers used for navigation frequently get silted up which reduces the clear depth required for the same. This often requires costly dredging due to the sediment deposited in the rivers and harbours.
