Concept: Relation between real depth,apparent depth and refrective index.Refractive index = Real depth/ apparent depth1.5 = 3/ apparent depthApparent depth = 3/1.5 = 2 cm.Distance through which the microscope is moved is=> 3 cm -2 cm = 1 cm upwards.Hence, correct answer is (b).

The image of the ink spot moves up by 1cm.

Refractive index = Real depth/ apparent depth

1.5 = 3/ apparent depth

Apparent depth = 3/1.5 = 2 cm

Distance through which the microscope is moved is 3 cm -2 cm = 1 cm upwards
