Best answer
Correct choice is (d) demagnetized

Explanation: Some Aircraft materials typically undergo the magnaflux inspection process. After the inspection process is done the parts have to be demagnetized before being used for manufacturing. This is because otherwise, they will interfere with the plane’s compass.
