(B) $1$. Compare '$256$' ('red colour chalk') and '$245$' ('white colour chalk'). The common digits are '$2$' and '$5$',and the common words are 'colour' and 'chalk'.$2$. Compare '$256$' ('red colour chalk') and '$589$' ('green colour flower'). The common digit is '$5$' and the common word is 'colour'. Therefore,'$5$' = 'colour'.$3$. Since '$5$' = 'colour',from the comparison in step $1$,'$2$' must be 'chalk'.$4$. Now,look at '$245$' ('white colour chalk'). We know '$5$' = 'colour' and '$2$' = 'chalk'. The remaining digit '$4$' must correspond to the remaining word 'white'.$5$. Thus,the digit '$4$' means 'white'.

In a certain code,'$256$' means 'red colour chalk','$589$' means 'green colour flower' and '$245$' means 'white colour chalk'. Which digit in that code means 'white'?
