The correct answer is: A. Their behaviour to stimuli is often inconsistent and unpredictable.
Human resources are the people who work in an organization. They are the most important asset of any organization, and their quality is essential to the success of the organization. Human resources are heterogeneous, meaning that they are different from each other in terms of their skills, knowledge, experience, and abilities. They are also dynamic, meaning that they are constantly changing and evolving. This makes it difficult to predict their behavior and to ensure that they are always performing at their best.
However, there are a number of things that organizations can do to improve the quality of their human resources. One is to invest in training and development, which can help employees to develop their skills and knowledge. Another is to create a positive work environment, which can help employees to be motivated and engaged. Finally, organizations can provide employees with opportunities for advancement, which can help them to feel valued and appreciated.
By taking these steps, organizations can improve the quality of their human resources and ensure that they are a valuable asset to the organization.
Option B is incorrect because human resources do not depreciate with passage of time in terms of skills. In fact, the opposite is true. With experience and training, human resources can become more skilled and knowledgeable.
Option C is correct because human resources are heterogeneous. They are different from each other in terms of their skills, knowledge, experience, and abilities. This diversity can be a strength, as it allows organizations to draw on a wide range of talents and perspectives. However, it can also be a challenge, as it can make it difficult to manage and coordinate human resources.
Option D is correct because retaining qualified human resources is a challenge for managers. Employees are often attracted to other opportunities, and they may leave an organization if they feel that they are not being compensated fairly or if they are not being given opportunities for advancement. Managers need to find ways to keep their employees motivated and engaged in order to retain them.
