Explanation:
A positive correlation of +1 means that returns move in the same direction in exactly the same proportions. In contrast, a perfect negative correlation of -1 suggests that the deviation in the returns of two assets is inversely proportionate.
A linear correlation greater than zero indicates a positive relationship. A value that is less than zero signifies a negative relationship. A zero correlation exists when there is no linear relationship between two variables, making option C the incorrect interpretation and therefore the right answer.
