{'protozoa': [1, 0, 0, 0], 'malaria': [5, 0, 2, 1], 'disease': [4, 2, 0, 0], 'cholera': [3, 1, 1, 4], 'common cold': [1, 0, 0, 0], 'pneumonia': [3, 0, 0, 0]}
The correct answer is option 3: Malaria. Malaria is a disease caused by protozoa, specifically the Plasmodium parasite. It is transmitted through the bite of infected female Anopheles mosquitoes.
Option 1, common cold, is caused by viral infections, not by protozoa.
Option 2, pneumonia, can be caused by bacteria, viruses, or fungi, but not specifically by protozoa.
Option 4, cholera, is caused by the bacteria Vibrio cholerae, not by protozoa.
Therefore, option 3, malaria, is the only option that correctly identifies a disease caused by protozoa.
