Answer:
The correct answer is letter "A": do nothing, if the listing item is not on the property as of the date of the contract, it is not included nor necessary to cross it out.
Step-by-step explanation:
The inclusions section of a buy or sell contract includes several items that might not be part of the property. The fact that those objects are part of the section does not imply they are part of the property in question. That is the reason why the section has the name of "if on the Property whether attached or not on the date of this Contract".
