Answer:
b. ability to get the job done.
Explanation:
No one is going to hire someone that has no experience in a field and that can't get the work done. This cannot be considered as a discriminating act, because if you applied for the job then you should be able to do it properly. If you are looking for a job is because you have the knowledge and the abilities to perform that job to the max. But if you cannot perform well at it, then the company is in all its rights to fire you. Because you were not able to surpass the expectations.
