Solution

## The correct option is C red colour suffers less deviationDifferent colours of light bend through different angles with respect to the incident ray, as they pass through a prism. The light ray with more wavelength suffers less deviation than light ray with more wavelength. So the red light bends the least while the blue the most.wavelength of red > wavelength of blue.So option (c): "red colour suffers less deviation" is correct.
