A square \( A B C D \) of side \( 1 \mathrm{~mm} \) is kept at distance \( 15 \mathrm{~cm} \) infront of the concave mirror as shown in the figure. The focal length of the mirror is \( 10 \mathrm{~cm} \). The length of the perimeter of its image will be(nearly):
(a) \( 8 \mathrm{~mm} \)
(b) \( 2 \mathrm{~mm} \)
(c) \( 12 \mathrm{~mm} \)
(d) \( 6 \mathrm{~mm} \)
