Choose the correct answer from the options given below:

• A. A - II, B - I, C - IV, D - III
• B. A - II, B - IV, C - III, D - I
• C. A - II, B - III, C - IV, D - I
• D. A - III, B - I, C - IV, D - II

Hint:

- Eichhornia (Water Hyacinth) \(\rightarrow\) Free-floating aquatic weed.
- Hydrilla \(\rightarrow\) Submerged aquatic weed.
- Parthenium \(\rightarrow\) Terrestrial roadside weed.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Weeds adapt to survive in diverse ecological niches and habitats.
These habitats range from dry, terrestrial environments to various aquatic ecosystems.
Detailed Explanation:
Let us match each habitat type with its corresponding weed species:
- A. Roadside: Roadside environments are disturbed, terrestrial habitats.
Congress grass (Parthenium hysterophorus) is an invasive terrestrial weed commonly found along roadsides, railway tracks, and wasteland areas.
This matches with II. Parthenium sp.
- B. Xerophytic: Xerophytic plants are adapted to survive in dry, arid environments with limited water.
Rasna (Pluchea lanceolata) is a tough, deep-rooted perennial weed adapted to dry, sandy soils in arid and semi-arid regions.
This matches with III. Pluchia lanceolata.
- C. Floating aquatic: These weeds float freely on the surface of water bodies.
Water hyacinth (Eichhornia crassipes) is a notorious free-floating aquatic weed that infests ponds, lakes, and slow-moving rivers.
This matches with IV. Eichhornia crassipes.
- D. Submerged aquatic: These weeds complete their entire life cycle below the water surface, anchoring to the bottom.
Water thyme (Hydrilla verticillata) is a submerged aquatic weed that forms dense mats underwater.
This matches with I. Hydrilla verticillata.
Combining these pairs yields the sequence: \[ \text{A - II}, \ \text{B - III}, \ \text{C - IV}, \ \text{D - I} \] This matches Option (C).

Step 2: Final Answer:
The correct matching sequence is A - II, B - III, C - IV, D - I.
