Consider the following statements: 1. Molasses is a by-product of sugar production process. 2. Bagasse obtained in the sugar mills is used as a fuel in the boilers to generate steam for the sugar factories. 3. Sugar can only be produced from sugarcane as the raw material. Which of these statement are correct?

Result
Your answer: —  Â·  Correct: A
Explanation

Statements 1 and 2 are correct: molasses is explicitly listed as a by‑product of sugar extraction and used for alcohol/yeast production, while bagasse (crushed cane residue) is a by‑product used for fuel and other applications such as paper making [1]. Statement 3 is incorrect because sucrose for commercial sugar production is obtained not only from sugarcane but also from sugarbeet, which contributes a significant share of world sugar production, demonstrating that sugar is not produced exclusively from sugarcane [2]. Therefore the correct choice is option 1 (statements 1 and 2 only).
