Generally speaking,if two variables are unrelated (as one increases,the other shows no pattern) ,the covariance will be:

A) a large positive number.
B) a large negative number.
C) a positive or negative number close to zero.
D) None of these choices.

If two variables are unrelated, the covariance will be close to zero, regardless of the signs of the individual data points. A large positive covariance implies that as one variable increases, the other tends to increase as well, while a large negative covariance implies the opposite pattern.
