Why is the combined use of red colour and a clear symbol effective in a warning sign?

Answer and explanation

Correct answer: Colour attracts attention and the symbol clarifies meaning

The governing concept is the combined effect of visual communication elements. Red colour can attract attention and signal caution, while a clear symbol communicates meaning quickly, even when a person does not read a long sentence. Together they make the warning more noticeable and easier to interpret. The sign is not oral, does not prevent feedback, and is not only written, so option D is correct.
