Concept: Diseases are caused by different types of pathogens such as bacteria, viruses, fungi, protozoa, and parasites. Correctly identifying the causative agent is important for diagnosis and treatment. Some common disease-causing organisms include:
• Bacteria – e.g., Typhoid, Tuberculosis
• Viruses – e.g., AIDS, Influenza
• Protozoa – e.g., Malaria
• Fungi – e.g., Ringworm

Step 1: Analyze each option.
• Malaria – Virus: Incorrect. Malaria is caused by a protozoan parasite Plasmodium.
• Typhoid – Bacteria: Correct. Typhoid fever is caused by the bacterium Salmonella typhi.
• Tuberculosis – Fungi: Incorrect. Tuberculosis is caused by the bacterium Mycobacterium tuberculosis.
• AIDS – Bacteria: Incorrect. AIDS is caused by a virus called Human Immunodeficiency Virus (HIV).

Step 2: Identify the correct disease-cause pair. Among the given options, the correct pair is: \[ \text{Typhoid} \rightarrow \text{Bacteria (Salmonella typhi)} \] Therefore, the correct answer is option (B).
