The Correlation Between $X$ And $Y$ Is $r = 0.35$ If We Double Each

The correlation between $X$ and $Y$ is $r = 0.35$ . If we double each $X$ value, decrease each $Y$ by $0.20$ , and interchange the variables (put $X$ on the $Y$ -axis and vice versa) , the new correlation

A) is 0.35
B) cannot be determined.
C) is 0.70
D) is 0.90
E) is 0.50
