The size of the image of an object, which is at infinity, as formed by a convex lens of focal length \( 30 \mathrm{~cm} \) is \( 2 \mathrm{~cm} \). If a concave lens of focal length \( 20 \mathrm{~cm} \) is placed between the convex lens and the image at a distance of \( 26 \mathrm{~cm} \) from the convex lens, calculate the new size of the image
(A) \( 1.25 \mathrm{~cm} \)
(B) \( 1.05 \mathrm{~cm} \)
(C) \( 2.5 \mathrm{~cm} \)
(D) \( 2 \mathrm{~cm} \)
