Which of the following inferences is/are correct? 1. The source of the energy we consume is the key to the battle for cleaner air. 2. Bans are effective where the will is strong and the people are convinced that such bans are for the greater good of society. 3. There is judicial approval for a policy that intervenes fiscally to facilitate benevolent pricing for cleaner fuel. Select the answer using the code given below.

Inference 1 is supported — the passage opens by saying the key source of the battle for clean skies and lungs is the fuel we burn. Inference 2 is not supported — the passage talks about the need for feasible alternatives (like CNG supply when diesel was banned) for bans to be effective, not about people's will or conviction. Inference 3 is supported — the passage states that the Supreme Court agreed that fiscal measures were needed to keep clean fuel cheaper than dirty fuel, which is judicial approval for fiscally-facilitated benevolent pricing for cleaner fuel. So inferences 1 and 3 are correct.
