Given below are two statements
Statement (I) : First generation bioethanol is produced from sugar, starch and vegetable oils.
Statement (II) : Second generation biofuels are derived from Algae.
In light of the above statements, choose the most appropriate answer from the options given below:
नीचे दो कथन दिए गए हैं
कथन (I) : प्रथम पीढ़ी का जैव-एथेनॉल (First generation bioethanol) शर्करा, स्टार्च और वनस्पति तेलों से निर्मित होता है।
कथन (II) : दूसरी पीढ़ी के जैव-ईंधन (Second generation biofuels) शैवाल (Algae) से प्राप्त होते हैं।
उपरोक्त कथनों के आलोक में, नीचे दिए गए विकल्पों में से सबसे उपयुक्त उत्तर चुनिए:
Generations of Biofuels:
- Statement (I) is CORRECT: 1st Generation Biofuels are produced directly from edible food crops rich in simple sugars (sugarcane, sugar beet), starch (corn, wheat), and vegetable oils (oil palm, rapeseed).
- Statement (II) is INCORRECT: 2nd Generation Biofuels are derived from non-food lignocellulosic biomass (agricultural residues like rice straw, wheat straw, bagasse, and dedicated woody energy crops like Jatropha or Miscanthus). Biofuels derived specifically from microalgae and cyanobacteria constitute 3rd Generation Biofuels.
Therefore, Statement (I) is correct but Statement (II) is incorrect.
Correct Answer: Option 3.
