What type of capital is concerned with individuals' capabilities and knowledge within the workforce?

The correct choice pertains to human capital, which is fundamentally concerned with the skills, knowledge, experience, and abilities of individuals within the workforce. It represents a critical asset for organizations, as these attributes contribute directly to innovation, productivity, and overall organizational performance.

Human capital emphasizes the value that employees bring to a business, including their talent, education, training, and work ethic. Companies invest in human capital through training and development programs, which can enhance employees’ capabilities, thus improving both individual and organizational outcomes.

The other types of capital, while important in various contexts, do not specifically focus on individuals' capabilities and knowledge. Intellectual capital involves knowledge assets and intellectual property that can lead to competitive advantage, social capital relates to the relationships and networks that enable cooperation within a community or organization, and financial capital deals with economic resources utilized for business investments. Each of these plays a significant role in a company's success, but human capital is distinctly centered on the workforce's personal skills and knowledge.
