Answer:
The correct answer is:
A more skilled and educated workforce increases output.
Professional development can improve the skills and knowledge of employees, which can lead to an increase in productivity and efficiency. When employees become more skilled and knowledgeable, they can perform their job tasks more effectively and efficiently, which can lead to a reduction in production costs. For example, a company may invest in training programs to teach employees new skills or technologies that can help them perform their job tasks more efficiently. This can lead to a reduction in the time and resources required to complete tasks, which can ultimately lead to lower production costs.
Option A is incorrect because if employees demand higher salaries after professional development, this would increase production costs rather than decrease them.
Option B is incorrect because if professional development is paid for by employees or a donation, this would not necessarily have an impact on production costs.
Option D is incorrect because while giving employees a day off for professional development may help to keep them motivated and engaged, it would not necessarily lead to a decrease in production costs.
