When the variables increase together it is said to have
 A Positive correlation B Negative correlation C Either A or B D None of the above
Explanation:

Detailed explanation-1: -What Is Positive Correlation? A positive correlation is a relationship between two variables that move in tandem-that is, in the same direction. A positive correlation exists when one variable decreases as the other variable decreases, or one variable increases while the other increases.

Detailed explanation-2: -Complete correlation between two variables is expressed by either + 1 or-1. When one variable increases as the other increases the correlation is positive; when one decreases as the other increases it is negative. Complete absence of correlation is represented by 0.

Detailed explanation-3: -A positive correlation exists when two variables move in the same direction as one another. A basic example of positive correlation is height and weight-taller people tend to be heavier, and vice versa. In some cases, positive correlation exists because one variable influences the other.

Detailed explanation-4: -If the correlation coefficient is greater than zero, it is a positive relationship. Conversely, if the value is less than zero, it is a negative relationship. A value of zero indicates that there is no relationship between the two variables.

Detailed explanation-5: -A positive correlation indicates the extent to which those variables increase or decrease in parallel; a negative correlation indicates the extent to which one variable increases as the other decreases.
