-Which of the following statements are true?
I: Suppose $\mathrm { f } : \mathfrak { R } ^ { \mathrm { n } } \rightarrow R ^ { \mathrm { m } }$ is a linear transformation and $S$ is an affine subset of $R ^ { \mathrm { n } }$ . It follows that the set of images $f ( S )$ is an affine subset of $R ^ { m }$ .
II: If $A \subset B$ , then aff $A \subset B$ .

A) I
B) Neither I or II
C) Both I and II
D) II
