Answer:
The correct answer is:
Professional development provides training that can increase employee value (capital) and impact earnings.
Professional development can have a significant impact on human capital and income potential. By providing training and development opportunities to employees, companies can help them acquire new skills and knowledge that can increase their value to the organization. This can lead to higher earnings potential for employees, as they become more valuable to the company and are able to take on more challenging roles and responsibilities.
Options B, C, and D are incorrect because they do not accurately reflect the impact of professional development on human capital and income potential. Option B suggests that professional development may fail to increase an employee's abilities, which is not necessarily true if the training is well-designed and implemented effectively. Option C suggests that professional development is unlikely to affect salaries, which is not true if the training leads to increased skills and knowledge that are valued by the company. Option D suggests that professional development is ineffective at increasing employee value, which is not true if the training is relevant and impactful.
