**Assertion (A):** The `rename()` requires copy argument to make changes in the original dataframe. **Reason (R):** To access values using positional index we can use `DF.iloc` A). Both A and R are true and R is the correct explanation for A B). Both A and R are true and R is not the correct explanation for A C). A is True but R is False D). A is false but R is True

The correct answer is A is false but R is True. **Assertion (A) is False:** To make changes permanently in the original DataFrame, the `rename()` method requires the `inplace=True` argument, not a "copy" argument. **Reason (R) is True:** `iloc` is indeed the property used in Pandas to access values using purely integer-location based (positional) indexing.
