B Correct answer
Explanation

Malaria is caused by Plasmodium parasites transmitted through the bite of infected female Anopheles mosquitoes. Tetanus comes from Clostridium bacteria in soil, diarrhea from contaminated water/food, and ascariasis from roundworm eggs in soil - none are mosquito-borne.

Multiple choice
  1. Destroying breeding places of mosquitoes

  2. The oral-rehydration therapy

  3. Spraying insecticides

  4. Sleeping under a mosquito net

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Oral-rehydration therapy (ORT) is a treatment for dehydration caused by diarrheal diseases like cholera or rotavirus, not a malaria prevention method. Malaria prevention involves stopping mosquito bites through nets, insecticides, and eliminating breeding sites - none of which ORT addresses.
