Employers can take a variety of approaches to deal with the shifting nature of jobs and job requirements. The approach would maintain current employees, providing them with instruction on the newly required skills, whereas the approach would replace the under-skilled employees with new, skilled employees.

a. selection; training

b. training; selection

c. hiring; training

d. training; hiring

b.training; selection

Explanation:

In an organization, the training approach refers to the fact that the organization or workplace takes the employees that it already has and trains them by providing them with new skills for the job they have or for a different job.

On the other hand, the selection approach takes people who are not working at the organization or workplace and selects them (matching their skills with the skills required for the job) and therefore, these new employees replace the under-skilled ones.

Therefore, the training approach would maintain current employees, providing them with instruction on the newly required skills, whereas the selection approach would replace the under-skilled employees with new, skilled employees.
