Correct Answer: (d) As they driven through the dark, twisting lane
Solution:If two actions took place in the past then the 1st action must be in the Past perfect tense(Had + V walked) and the 2nd action must be in the Simple Past tense(V₂).- However, the V₂ form of 'drive' is 'drove'.
- Hence, 'as they drove (V) through the dark, twisting lane' is the most appropriate answer.
