Option 1 -> The passage states she "travelled around the Philippines in order to organise the Indian citizens" and "mobilised people in Manila."
Option 2 -> Explicitly mentioned that she distributed "literature relating to freedom movement" and "independence literature."
Option 3 -> The passage clearly states she inspired people by "delivering inspiring speeches to Indian passengers of ships."
Option 4 -> This activity is nowhere mentioned in the passage about her work in the Philippines.
Hence, Option 4: visiting popular hot spots -> Gulab Kaur's documented activities in the Philippines focused on revolutionary work - organizing Indians, gathering weapons and funds, distributing literature, and delivering speeches. There is no mention of her visiting popular hot spots, as her mission was political mobilization against British rule, not tourism or leisure activities -> correct
