Answer:
A) attempt to cure the defect
Step-by-step explanation:
In this scenario Grange Co-op is recieving high quality seed from Fruited Plain. Only half of the high quality seed is available, the other half is made up of lower quality seed that is half the price of the higher quality one.
Since time for performance is not yet expired the best option for Fruited Plain is to attempt to cure the defect in the lower quality seeds and make them high quality.
They also have a lower cost of half what would have been spent on the remaining seeds. This fund can be used to cure the defect in lower quality seeds
