Correct Answer
(A) A-(II), B-(III), C-(IV), D-(I)
Solution & Explanation
Answer: (A) A-(II), B-(III), C-(IV), D-(I) Solution: Typhoid is caused by the bacterium Salmonella typhi (A-II). Elephantiasis/filariasis is caused by Wuchereria, a helminth of phylum Aschelminthes (B-III). Ringworm is caused by fungi such as Microsporum (C-IV). Malaria is caused by the protozoan Plasmodium (D-I). Why others are wrong: Options swapping Salmonella↔Protozoan for typhoid/malaria or Microsporum↔Aschelminthes for ringworm/elephantiasis break the correct pathogen-disease links given in NCERT. NCERT Reference: NCERT Ch7, p.130-133, lines (p130) 40-41, (p131) 28-29, (p133) 16-26: "Salmonella typhi is a pathogenic bacterium which causes typhoid"
