Option 3 : Red, green and blue

CONCEPT:

Primary colours are those colours which when mixed in specific proportions can form any colour.
The spectral colours i.e. blue, red and green are the primary colours.
Secondary colours such as yellow, magenta etc. can be produced by mixing two primary colours in the right proportion.
Any two colours which when added produce white light are known as complementary colours.

EXPLANATION:

In TV, a colour broadcast can be created by broadcasting three monochrome images, one each in the three colours of red, green, and blue (RGB). Therefore option 3 is correct.
These three primary coloured images are used to create all other colours.
