Solution

This question is based on the rules of conditional sentences, specifically the third conditional. The third conditional is used to talk about a situation that did not happen in the past and to imagine the result if it had happened. It typically follows the pattern: "If + past perfect, would have + past participle." In this case, the correct sentence should have been: "If I had known about the traffic delays earlier, I would have taken an alternative route through the scenic countryside."
