    Answer : Option B

    Explanation :

    According to choice (a), the fishermen and the anglers will not be able to catch Suplora. This weakens the prediction of the fisheries department. According to choice (b), the local people also wish to conserve the rivers. From this it can be said that the local people would definitely report if they catch Suplora. Hence, (b) provides support to the prediction of the department.

    Choice (c) does not state whether the department will receive information from the fishermen and the anglers.
