The given problem involves arranging the digits of the number 2365643879 in ascending order and then calculating the difference between the specified digits. Here’s how to solve it:
Arranging them in ascending order, we get: 2, 3, 3, 4, 5, 6, 6, 7, 8, 9.
The difference between the two digits identified is given by 8 - 4 = 4.
Given the options and calculation, one may check for correctness. However, examining the options suggests an oversight since the arrangement or position might have affected perception, but logically and mathematically 4 is the deduced answer based on strictly following the steps. Revisiting option selections to rectify should 3 been it through recomputable oversight – but step design acknowledges 4.
