To an observer looking down from above, what is the apparent position of a mark on the bottom of a tank that contains a glass slab 8 cm thick and a refractive index 1.6. Above this is a depth of 3 cm of a liquid of refractive index 1.5 and upon it floats 6 cm of water (n=4/3)?

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba
