K SUNKANNA · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
**Primary Concept**: Biogas production using plant biomass.
**Related Topics**: Renewable energy, anaerobic digestion, plant identification.
**Prerequisites**: Basic knowledge of biogas production and common weeds.
## SOLUTION PATHWAY
**Given Information**:
       *  The question asks for a weed, besides dung, that can be used in biogas production.
       *  Options are four different plant species.
**Method & Steps**:
 1. Identify the options and recall if any are known to be used for biogas.
    Reasoning: Biogas production relies on organic matter. Some weeds are known to be prolific and have high biomass suitable for biogas generation.
    2. Select the correct option
    Result: Eichhornia crassipes is known to be used in biogas production, due to its high growth rate and biomass.
## OPTION ANALYSIS
[A] :x: Hydrilla is an aquatic plant, but less commonly used for biogas.
[B] :x: Solanum nigrum (black nightshade) is a common weed, but not typically used for biogas production.
[C] ✓: Eichhornia crassipes (water hyacinth) is a well-known weed that is used in biogas production due to its rapid growth and high biomass.
[D] :x: Parthenium Hysterophorus (congress grass) is a weed, but not commonly used for biogas.
## LEARNING AIDS
**Common Mistakes**:
 1. Incorrectly associating all weeds with biogas production. Many weeds are not suitable or efficient for biogas.
    How to avoid: Focus on those that have high biomass and are known to be used.
**Quick Tips**:
 1. Remember that aquatic plants like water hyacinth are often good candidates for biogas due to their abundance.
