    B: - 1

    Step-by-step explanation:

    Here as the value of X is increasing, the value of Y is get decreased. Thus Negative Correlation is exist here.

    Also, if we notice here the values of both the observation are just reciprocal.

    Thus, the Value of Correlation Coefficient is exact - 1.

    The Correlation Coefficient is the strength and direction of relationship between two variables. And its value lie between - 1 to + 1.
