Answer: D) As stated in our contract,we are liable to pay compensation only when our personnel repair the equipment
Step-by-step explanation:
Based on the information given in the question, the best way to phrase the refusal of Marie's claim for adjustment is that "As stated in our contract, we are liable to pay compensation only when our personnel repair the equipment".
Since a service executive in the company discovers that the mower was dismantled by someone, then Marie's claim for adjustment can be refused since it wasn't dismantled by someone from the company.
