| Disease | Pathogen | Main organ affected | |
| 1. | Dysentery | Protozoa | Liver |
| 2. | Ringworm | Fungus | Skin |
| 3. | Typhoid | Bacteria | Lungs |
| 4. | Filariasis | Common round worm | Small intestine |
The correct answer is (B) : 2.
The correct answer is: (B) 2.
Let's match the diseases with their respective pathogens and main organs affected:
Thus, the correct match is option 2, where the disease is ringworm, the pathogen is a fungus, and the main organ affected is the skin.
| List I | List II | ||
| A. | Common cold | I. | Plasmodium |
| B. | Haemozoin | II. | Typhoid |
| C. | Widal test | III. | Rhinoviruses |
| D. | Allergy | IV. | Dust mites |
The circuit shown in the figure contains two ideal diodes \( D_1 \) and \( D_2 \). If a cell of emf 3V and negligible internal resistance is connected as shown, then the current through \( 70 \, \Omega \) resistance (in amperes) is:
