In the figure shown, a point object O is placed in air on the principal axis. The radius of curvature of the spherical surface is 60 cm. Let I₍f₎ be the final image formed after all the refractions and reflections.

Select all that apply

• Option A

  If d₁ = 120 cm, then the final image I is formed on O for any value of d₂.

• Option B

  If d₁ = 240 cm, then the final image I is formed on O only if d₂ = 360 cm.

• Option C

  If d₁ = 240 cm, then the final image I is formed on O for all values of d₂.

• Option D

  If d₁ = 240 cm, then the final image I cannot be formed on O.
