Incomplete question, however I made interferences from an employer perspective.
Answer:
Applicant 1 is best suited to work in network systems, while Applicants 2 and 3 could work in programming, information support, or interactive media.
Step-by-step explanation:
From a performance point of view the programming, information support and interactive media roles of the company would be better handled by more than one individual since this roles involve more responsibilities that could not be handled by one individual.
The network systems role can better be managed by Applicant 1 only as it is a task that could be handled by a single employee.
