(A) such as the Manhattan Atomic Bomb project, advanced radar technology and new initiatives in rocket propulsion, for, war-prone countries considered advances in technology critical

(B) for the Manhattan Atomic Bomb project, advanced radar technology and for new initiatives in rocket propulsion, for, war-prone countries considered advances in technology critical

(C) like the Manhattan Atomic Bomb project, advanced radar technology and new initiatives in rocket propulsion, for, war-prone countries considered advances in technology to be critical

(D) such as the Manhattan Atomic Bomb project, advanced radar technology and new initiatives in rocket propulsion, for, war-prone countries considered advances in technology as critical

(E) such as the Manhattan Atomic Bomb project, advanced radar technology and new initiatives in rocket propulsion, for, war-prone countries considered advances in technology were critical

The OA is A.

I couldn't decide between A or D. Can someone help to discard the option D?
