Answer:
Option (2)
Explanation:
If a polygon is dilated by a scale factor = k
Rule to be followed,
(x, y) → (kx, ky)
Here, k = Scale factor
If 0 < k < 1, size of the image will be reduced.
If k > 1, size of the image will be enlarged.
Pentagon MNPQR is dilated with the origin as the center of dilation to form an image M'N'P'Q'R'.
Rule used for the transformation,
(x, y) →

Here, scale factor by which MNPQR has been dilated is

Since, scale factor is between 0 and
, size of M'N'P'Q'R' will be reduced.
Therefore, size of pentagon M'N'P'Q'R' will be smaller than pentagon MNPQR.
Option (2) will be the answer.
