Final Answer :
C
Explanation :
The statistical measure of the strength of the relationship between two random variables X and Y is referred to as the covariance. The expected value is the mean of a random variable, the variance is a measure of the spread of a random variable, and the standard deviation is the square root of the variance. None of these measures directly describe the relationship between two variables.
