Proposal: The two most formidable threats faced by freshwater dolphins are depletion of their prey by the enormous by-catch of fish in "mosquito" nets and the increase in pollution that reduces freshwater resources. To slow the dolphins' extinction, local fishermen should stop using "mosquito" nets and turn to other fishing methods.
Objection: Any other fishing method requires the use of more motor boats that will inevitably lead to further the increase in pollution and further threaten the dolphins.
Which of the following, if true, most adequately counters the objection to the proposal?
A. It is impossible for the local fishermen to completely stop using the "mosquito" nets because this would result in financial losses.
B. Replacing "mosquito" nets with other fishing methods would more than double the amount of fish available for dolphins to consume.
C. With the help of active environmental campaigns, local authorities could be persuaded to build more water purification facilities, thus making pollution less of a problem for dolphins.
D. Dolphins suffer significantly more when their food is scarce than when the level of pollution increases.
E. Regardless of whether the food is scarce or abundant, it is unlikely that dolphins will be able to survive if the present rate of pollution increases.

In order to counter the objection we have to show that pollution is not the major reason for dolphins extinction.
D options shows the same.

Isn't C similar to D ? In C , it says that the authorities could be persuaded to make pollution less of a problem for dolphins.
In D , it says the effect of pollution is not that significant. Is D option preferred because persuading the authorities is kind of a long shot ?
