A cube of side \( 2 \mathrm{~m} \) is placed in front of a concave mirror focal length \( 1 \mathrm{~m} \) with its face \( P \) at a distance of \( 3 \mathrm{~m} \) and face \( Q \) at a distance of \( 5 \mathrm{~m} \) from the mirror. The distance between the images of face \( P \) and \( Q \) and height of images of \( P \) and \( Q \) are
(a) \( 1 \mathrm{~m}, 0.5 \mathrm{~m}, 0.25 \mathrm{~m} \)
(b) \( 0.5 \mathrm{~m}, 1 \mathrm{~m}, 0.25 \mathrm{~m} \)
(c) \( 0.5 m, 0.25 m, 1 m \)
(d) \( 0.25 \mathrm{~m}, 1 \mathrm{~m}, 0.5 \mathrm{~m} \)
