Solution

The correct option is B

Blue


The white coloured light is a combination of seven colours. These colours are violet, indigo, blue, green, yellow, orange and red (VIBGYOR). When it falls on a blue coloured object, all other colours are absorbed except the blue colour which is reflected back to our eye and hence, we see the object as blue coloured.
