When Nigeria achieved full independence in 1960, they had already established a federal political structure consisting of three regions based on the three major population clusters that were in its borders.

(D) it had already established a federal political structure that consisted of three regions based on the three major population clusters within
(E) it already had established a federal political structure consisting of three regions being based on the three major population clusters it had within

Answer is D .
It is easy to eliminate E on the basis on the unnecessary being
My question is the order of the highlighted words . Does that help in any way in eliminating the choices . Which order is better ? Are both correct ?
