Answer:
C)The study will weigh the benefits against the negative impacts so an informed decision can be made.
Step-by-step explanation:
Dredging is the removal of sediments and debris that may be found beneath a water body such as oceans, rivers, lakes etc.
It is a key process as the ability of ship to move on the water body may be impaired where filled with such debris.
As such, a study may be required to help weigh the cost and possible benefits of dredging.
