Answer:
A. Reliance on available Subjects.
Explanation:
Reliance on available subjects is a sampling method used by researchers, in this case the reporters to get the opinion of randomly selected people, or passersby on topics of interest. It is not a very reliable method of sampling because the researcher cannot control how effectively the sample represents the entire population. It is also known as a Convenience Sample.
It is important to note that the opinions of the passersby can not be accepted as a statement of fact as they do not represent the true population. This sampling method is best used to get the opinion of people at a particular point in time. It is not used for in depth research.
