The Pearson correlation coefficient is
\[
r=\frac{\operatorname{Cov}(X,Y)}{\sigma_X\sigma_Y}.
\]
It is unaffected by adding or subtracting constants (change of origin) and by multiplying variables by positive constants (change of scale).
Hence,
\[
\boxed{\text{Correlation coefficient is independent of both origin and scale.}}
\]
Therefore,
\[
\boxed{(D)}
\]
is the correct answer.
