Answer: b. The company will be flooded with applications from individuals who are barely qualified.
Step-by-step explanation:
By putting job advertisements on popular websites which are full of people looking for jobs, the company will attract people who are underqualified but apply anyway on the off chance that they are called for an interview. The company will incur costs sifting through the applications to find suitable candidates.
This will be a waste of the company's resources as those resources could have been directed at getting prospective employees that would be a better fit with the company and have the relevant qualifications. This could have been done by going to a recruiting agency for instance.
