Answer:
The correct option is external recruiting
Step-by-step explanation:
External recruitment is the process of filling vacant roles in an organization by inviting external applicants to apply for the role rather choosing someone internally as would be the case under internal recruitment process.
External recruiting has its pros and cos,which includes the the fact that newly recruited hands would not be able to hit the group since they are now in an unfamiliar terrain as compared to an old member of staff who is accustomed to the way things are done.
It is more costly recruiting externally since internal recruiting does require other an internal memo not advert in several newspapers.
