(a) प्रभावीपणे काबीज केल्यास, सौर उर्जा भारतातील एकुण वीज आवश्यकतेची परिपूर्णता करू शकते.
(b) सौर उर्जा स्वयंपाक अनुप्रयोगासाठी उपयुक्त नाही.
(c) सौर उर्जा प्रकाश अनुप्रयोगासाठी उपयुक्त आहे.
(d) सौर उर्जा पर्यावरण अनुकूल आहे.
पर्यायी उत्तरे :

The correct answer is Option A ((a), (c) and (d)).

Key Points:
• Immense Potential of Solar Energy: India receives about 5,000 trillion kWh per year of incident solar energy, with roughly 300 clear sunny days. If harnessed efficiently, it has the capacity to fulfill India's entire power requirements (Statement a).
• Lighting Applications: Widely deployed via Solar Home Systems, Solar Lanterns, and Solar Street Lighting systems across the globe (Statement c).
• Environmentally Friendly: Solar energy is a zero-emission renewable energy source that produces no greenhouse gases during operations (Statement d).
• Cooking Utility: Statement (b) is completely false because solar cookers (box-type, parabolic concentrators, and solar steam community kitchens like at Shirdi) are widely utilized in India.
• Official Key: Statements (a), (c), and (d) are true, confirming Option (1).
• Key Takeaway: Solar energy is eco-friendly, powers lighting, and can theoretically meet total national power demand, while also being suitable for cooking.
