Pentagon MNPQR is shown on the coordinate grid. Pentagon MNPQR is dilated with the origin as the center of dilation using the rule (x,y) --> (1/4x, 1/4y) to create pentagon M′N′P′Q′R′. Which statement is true?

• Pentagon M′N′P′ Q ′R ′ is larger than pentagon MNPQR, because the scale factor is greater than 1.

• Pentagon M′N′P′ Q ′R ′ is smaller than pentagon MNPQR, because the scale factor is less than 1.

• Pentagon M′N′P′ Q ′R ′ is smaller than pentagon MNPQR, because the scale factor is greater than 1.

• Pentagon M′N′P′ Q ′R ′ is larger than pentagon MNPQR, because the scale factor is less than 1.
