$A$ glass hemisphere of radius $0.04\, m$ and refractive index $1.6$ is placed centrally over a cross mark on a paper:
$(i)$ with the flat face in contact with the paper;
$(ii)$ with the curved face in contact with the paper.
In each case,the cross mark is viewed directly from above. The positions of the images will be:

• A
  $(i)\, 0.04\, m$ from the flat face; $(ii)\, 0.025 \,m$ from the flat face
• B
  $(i)$ At the same position of the cross mark; $(ii) \,0.025\, m$ below the flat face
• C
  $(i)\, 0.025\, m$ from the flat face; $(ii) \,0.04\, m $ from the flat face
• D
  For both $(i)$ and $(ii)\, 0.025\, m$ from the highest point of the hemisphere
