Option 1 -> The train represented freedom and new beginnings, not a burden or obstacle to overcome.
Option 2 -> The passage explicitly states the train "symbolised an escape" and a way to "start afresh," with Arjun feeling "a sense of possibility" and a chance to "rediscover himself."
Option 3 -> While Arjun experienced some uncertainty, the train itself symbolized hope and opportunity, not fear.
Option 4 -> The train was an escape from conflict and struggle, not a representation of them.
Hence, Option 2: liberation and renewal -> The train approaching through the mist symbolized Arjun's journey toward freedom from his burdens and the opportunity for a fresh start. The passage emphasizes this through phrases like "escape," "start afresh," "sense of possibility," and "change wasn't the end—it was the beginning," clearly indicating themes of liberation and renewal. -> correct
