What are 3 Fs that Finance Minister said India should focus on amid US-Iran war?

FM Nirmala Sitharaman said India should focus on 3 Fs - fuel, fertiliser and foreign exchange - amid US-Iran war. Sitharaman said India's economic challenges are currently "more external" in nature because of country's dependence on imports for critical commodities like crude oil, fertilisers and gold. "Just imagine all of them coming together because of West Asia crisis," she added.
