Explanation / Answer

When any object moved towards earth, its apparent wavelength decreases and is termed a 'blue shift'.

When any object moved away from earth, its apparent wavelength increases and is termed a 'red shift'.

For transverse movement, there is no shift.

Therefore,

Blue shift occurs for II and V cases, red shift occurs for case III and no shift for cases I and IV
