Choose the correct statement. A. Human capital is the work effort that people devote to producing goods and services. B. The quality of labour depends on human capital C. Today in Canada less than 90 percent of the population have completed high school. D. Working at the same job for several years decreases your human capital

##Step 1: Defining Human Capital<br />###Human capital refers to the knowledge and skills that workers acquire through education, training, and experience. It's distinct from labor, which is the actual effort exerted. Human capital *enhances* the quality of labor.<br />##Step 2: Analyzing Option A<br />###Option A incorrectly defines human capital as the work effort itself. Human capital is the accumulated knowledge and skills, not the act of working.<br />##Step 3: Analyzing Option B<br />###Option B correctly states that the quality of labor depends on human capital. More knowledge and skills lead to higher quality work.<br />##Step 4: Analyzing Option C (External Knowledge Required)<br />###This statement requires external data verification. Generally, high school completion rates in developed countries like Canada are high. While precise figures fluctuate, it's unlikely to be *less* than 90%. This option is likely incorrect.<br />##Step 5: Analyzing Option D<br />###Option D is incorrect. Working at the same job, especially if it involves continuous learning and development, can *increase* human capital through experience and specialized skill acquisition.<br /><br />#
