Danger signals are red in colour becausea)red colour is least scattere...
The correct answer is option 'A', which states that red color is least scattered.
The reason for red color being used for danger signals is that it is the color that is least scattered by air molecules, dust and other particles in the environment. This means that red signals are visible from farther away and are less likely to be obscured by atmospheric conditions. The wavelength of red color is longer than other colors and it is not necessary to be the least scattered because of that. And the attraction of red color is not the reason for it being used for danger signals.
