The answer is not B, because even though the rock goes through a chemical change we’re trying to find the properties of the rock. The test does not include rust, so A is incorrect. A physical change would be a change in shape or color, and the rock did not change that way, so C is also wrong. Identity property(D), is your correct answer because Identity property can be explained as properties that are found during or after a chemical reaction/change. Since we found calcite by having the rock go through a chemical change, we have identified a property.
