Option 1 -> The passage indicates the opposite; the group became vibrant and dynamic, not rigid and cautious.
Option 2 -> While maintaining brand discipline, the focus was on transformation and innovation rather than just preserving traditions.
Option 3 -> The passage explicitly states the group "transformed into a symbol of vibrancy and innovation" and "evolved into a forward-thinking organization, pioneering bold strategies."
Option 4 -> This contradicts the text which mentions the group "embraced daring ideas, expanded overseas," and undertook significant transformations.
Hence, Option 3: It evolved into a vibrant and innovative organization -> The passage clearly describes how under Ratan Tata's leadership, the Tata Group shifted from being stable but lacking dynamism under J.R.D. Tata to becoming a symbol of vibrancy and innovation, embracing bold strategies and overseas expansion -> correct
