Translation : “Had I known about the traffic, I would have left earlier.” Best translation into Urdu/Hindi:

The English sentence "Had I known about the traffic, I would have left earlier" is a classic example of the third conditional. This grammatical structure expresses a hypothetical situation in the past that did not happen and its hypothetical past consequence. It conveys regret or a missed opportunity based on a past condition that wasn't met. The structure is typically "If + past perfect, would have + past participle."

• The best translation into Urdu/Hindi is "اگر میں ٹریفک جانتا ہوتا تو میں پہلے نکل چکا ہوتا". This option correctly uses "جانتا ہوتا" (had known) for the hypothetical past condition and "نکل چکا ہوتا" (would have left) for the hypothetical past consequence, accurately reflecting the third conditional.
• Option A uses simple past and simple conditional, translating to "If I knew the traffic, I would leave earlier."
• Option B uses present tense, translating to "If I know the traffic, I leave earlier."
• Option D is a statement of fact in the past, "Seeing the traffic, I left earlier," not a conditional.
