The correct Answer is:
To solve the matching question regarding diseases and their corresponding pathogens, we will follow these steps: ### Step 1: Identify the Pathogen for Each Disease 1. **Red rot of sugarcane**: This disease is caused by a fungus. The specific fungus responsible for this disease is *Colletotrichum falcatum*. 2. **Root-knot of tobacco**: This disease is caused by a nematode. Nematodes are a type of roundworm that can cause significant damage to plants. 3. **Black rot of crucifers**: This disease is caused by bacteria, specifically the genus *Xanthomonas*. 4. **Turnip mosaic**: This disease is caused by a virus known as the turnip mosaic virus (TMV). ### Step 2: Match Each Disease with Its Pathogen Now that we have identified the pathogens, we can match them with the diseases: - **(a) Red rot of sugarcane** matches with **(iv) Fungi**. - **(b) Root-knot of tobacco** matches with **(iii) Nematode**. - **(c) Black rot of crucifers** matches with **(ii) Bacteria**. - **(d) Turnip mosaic** matches with **(i) Virus**. ### Step 3: Write the Final Matches Based on the matches we made: - (a) Red rot of sugarcane → (iv) Fungi - (b) Root-knot of tobacco → (iii) Nematode - (c) Black rot of crucifers → (ii) Bacteria - (d) Turnip mosaic → (i) Virus ### Final Answer The correct matches are: - a → iv - b → iii - c → ii - d → i Thus, the final answer is: - (a) → (iv) - (b) → (iii) - (c) → (ii) - (d) → (i)
