Introduction:
Building human capital refers to the process of enhancing the skills, knowledge, and capabilities of individuals in a country. It plays a crucial role in the development and growth of a nation's economy. However, not all activities contribute equally to the building of human capital. In the given options, increasing salary of workers cannot be regarded as building human capital in a country.

Explanation:
1. Spending resources on education:
Investing in education is one of the primary ways to build human capital. By allocating resources to education, a country can improve the knowledge and skills of its population. This leads to a more educated workforce, better job opportunities, and higher productivity.

2. Providing training of industrial workers:
Providing training to industrial workers is another important aspect of building human capital. By equipping workers with industry-specific skills and knowledge, they become more efficient, productive, and adaptable to changes in the workplace. This ultimately benefits both the workers and the economy.

3. Increasing salary of workers:
Increasing the salary of workers, while important for their well-being, does not directly contribute to building human capital. Higher salaries may motivate individuals to work harder, but they do not necessarily enhance their skills or knowledge. Building human capital requires investments in education, training, and skill development rather than just increasing wages.

4. Providing health to all:
Ensuring access to healthcare for all individuals is crucial for building human capital. Healthy individuals are more likely to be productive, have better cognitive abilities, and contribute to the overall development of a nation. By providing healthcare, a country can improve the well-being and productivity of its population.

Conclusion:
While all the options mentioned in the question are important for the overall development of a country, increasing the salary of workers alone cannot be regarded as building human capital. Building human capital requires investments in education, training, and healthcare, which directly enhance the skills, knowledge, and well-being of individuals in a country.

• Increasing salary of workers: Increasing salary of workers does not directly contribute to building human capital in a country. While it may improve the standard of living for individuals, it does not necessarily enhance their skills, knowledge, or capabilities.

• Spending resources on education: Investing in education helps to develop the knowledge, skills, and abilities of individuals, which in turn contributes to the overall human capital of a country.


• Providing training of industrial workers: Providing training to industrial workers helps to enhance their skills and productivity, thereby increasing the human capital of the country.


• Providing health to all: Ensuring access to healthcare for all individuals improves their well-being and productivity, which in turn contributes to the human capital of the country.

By focusing on education, training, and healthcare, a country can effectively build its human capital and foster economic growth and development.
