请教gwd上一道语法题

The normative model of strategic decision-making suggests that executives examine a firm’s external environment and internal conditions, and in using the set of objective criteria they derive from these analyses, can decide on a strategy.

1. conditions, and in using the set of objective criteria they derive from these analyses, can decide

2. conditions, and they use the set of objective criteria derived from these analyses in deciding

3. conditions and, in using the set of objective criteria derived from these analyses, deciding

4. conditions and, using the set of objective criteria derived from these analyses, decide

5. conditions and, in their use of the set of objective criteria they derive from these analyses, they decide

   Answer: d

but I choose b

我觉得这里考的是examine 和decide的并列结构

B中如果把in deciding改成to decide倒也可以，不过这样就没有考点了

出题者故意在examine和decide之间插入using the set of ...的成分，来弱化并列结构的感觉，增加题目难度。

原来还是在考平行结构啊，

谢谢谢谢
