Question

Match List-I with List-II

Choose the correct answer from the options given below:

• (A) - (IV), (B) - (I), (C) - (II), (D) - (III)
• (A) - (III), (B) - (II), (C) - (IV), (D) - (I)
• (A) - (II), (B) - (III), (C) - (I), (D) - (IV)
• (A) - (I), (B) - (IV), (C) - (III), (D) - (II)

Hint:

Focus on unique processes: Transesterification is the signature process for bio-diesel production (B matches with II), and anaerobic digestion (biogas) is always biochemical (C matches with IV). This simplifies the matching.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Biomass can be converted into useful energy carriers (fuels) via physical, thermo-chemical, chemical, or biochemical conversion technologies.

Step 3: Detailed Explanation:
Let us match the bio-products with their specific conversion processes:
1.

Briquettes (A): Produced by applying high physical mechanical pressure to densify loose agricultural residue. Thus, it matches with

(III) Physical conversion.
2.

Bio-diesel (B): Synthesized from fats or vegetable oils via chemical exchange with an alcohol. Thus, it matches with

(II) Transesterification.
3.

Biogas (C): Produced through anaerobic digestion of organic matter by bacterial communities. Thus, it matches with

(IV) Bio-chemical conversion.
4.

Producer gas (D): Produced by partial combustion and gasification of solid biomass under high temperatures. Thus, it matches with

(I) Thermo-chemical conversion.
Combining these: (A) - (III), (B) - (II), (C) - (IV), (D) - (I).

Step 4: Final Answer:
The correct option is 2, which corresponds to (A) - (III), (B) - (II), (C) - (IV), (D) - (I).
