Answer:
B
Explanation:
Hands are the primary method of transmission of the common cold. The most frequent means of transmission of the tubercle bacillus is by droplet nuclei. The bacillus is present in the air as a result of coughing, sneezing, and expectoration of sputum by an infected person. The tubercle bacillus is not transmitted by means of contaminated food. Contact with contaminated food or water could cause outbreaks of salmonella, infectious hepatitis, typhoid, or cholera. The tubercle bacillus is not transmitted by eating utensils. Some exogenous microbes can be transmitted via reservoirs such as linens or eating utensils.
