Which of the following can make you ill if you come in contact with an infected person?
(a) High blood pressure
(b) Genetic abnormalities
(c) Sneezing
(d) Blood cancer
Answer: C
Solution: Sneezing releases disease-causing microbes into the air from an infected person which is in turn inhaled by a healthy person causing illness. This causes communicable disease where the microbes initiate a new infection. A few examples of diseases caused by sneezing are tuberculosis and Pneumonia.
Hence, C is the correct answer.
