When a pin is moved along the principal axis of a small concave mirror, the image position coincides with the object at a point \( 0.5 \mathrm{~m} \) from the mirror, refer figure. If the mirror is placed at a depth of \( 0.2 \mathrm{~m} \) in a transparent liquid, the same phenomenon occurs when the pin is placed \( 0.4 \mathrm{~m} \) from the mirror. The refractive index of the liquid is
(a) \( 6 / 5 \)
(b) \( 4 / 3 \)
(c) \( 4 / 3 \)
(d) \( 3 / 2 \)
