Option 1 -> The passage doesn't mention him specifically designing for locals; his focus was on staying in Kolkata and building his brand from there.
Option 2 -> While he did honor Kolkata, this doesn't capture the meaning of "turning the narrative on its head" which implies reversing expectations.
Option 3 -> The prevailing narrative was that designers must leave Kolkata for success ("Everyone told me staying in Kolkata was suicidal"). He reversed this by achieving massive success while staying put.
Option 4 -> His confidence is not the point; the phrase refers to defying conventional wisdom about location and success.
Hence, Option 3 -> He challenged and reversed the established belief that one must leave Kolkata to succeed in fashion. Despite everyone's advice that staying was "suicidal," he persevered and became so successful that he's now "bringing the whole world to Kolkata" -> correct
