Answer:
The correct option is C, use their best judgement
Step-by-step explanation:
Option A is wrong as there was no requirement stipulating that they need to check with the corporate office before accepting a return.
Option B is also wrong based on the point above.
Option C is correct as the employees are given the opportunity to use their best judgement in determining whether or not an item is still in good condition.
Option D is also wrong because there was no pointer to strict adherence to guidelines.
Lastly, option E is wrong because good condition is not the same new condition.
