In the figure shown- \( 5.364 \) a point object \( O \) is placed in air on the principal axis. The radius of curvature of the spherical surface is \( 60 \mathrm{~cm} . I_{f} \) is the final image formed after all the refractions and reflections:
Figure \( 5.364 \)
(A) If \( d_{1}=120 \mathrm{~cm} \), then the ' \( I_{f} \) ' is formed on ' \( O \) ' for any value of (B) If \( d_{1}=240 \mathrm{~cm} \), then the ' \( I_{f} \) ' is formed on ' \( O \) ' only if \( d_{2}=360 \mathrm{~cm} \)
(C) If \( d_{1}=240 \mathrm{~cm} \), then the ' \( I_{f} \) ' is formed on ' \( O \) ' for all value of \( d_{2} \)
(D) If \( d_{1}=240 \mathrm{~cm} \), then the ' \( I_{f} \) ' cannot be formed on ' \( O \) '
