Answer:
Wayne's most effective argument is:
c) Exceeding the scope of the easement.
Step-by-step explanation:
Easement grants a party the right to use another party's property for a specific purpose. The right granted Mitch was to pump water across Wayne's property on his farm. Since now he intends to convert the farm into a fish camp and flood it with water, thus, raising Wayne's concerns over the consequences on his own property, Wayne can stop Mitch by indicating that the scope of the easement did not include flooding the fields for the purpose of a fish camp.
