Why?​

Answer 1

Answer:

The most likely condition to fall sick is when our friend is having measles. 

Reason. Measles is a very infectious diesease. If we visit or meet our friend then the disease can spread through air in the form of droplet thrown in air during sneezing, coughing, nasal discharge etc. (Microbes enter through respiratory tract or conjuctiva of eye). So, we are most likely to get infected by the disease.
