Concept:The sentence describes a careless woman who foolishly never worried about being robbed.
The words (B) "robbed" and (D) "naively" are misplaced and need to be swapped.
Explanation:The word "unwary" (A) means not cautious, which correctly describes the woman.
The word "naively" (D) means in a foolishly innocent way, so it should modify "never worried".
The word "robbed" (B) is the action she should have worried about, so it belongs after "getting".
Thus, the correct order is: "The unwary woman naively never worried about getting robbed".
Therefore, positions (B) and (D) must be interchanged.
Answer:Option B (B-D) is the correct arrangement.
