The correct answer is A. One person adds pedals and one adds wheels to a bicycle.
Explanation:
In economy, division of labor occurs when the process of manufacture a product or any other economic activity depends on different individuals as each individual performs a specific task that contributes to the process, which allows individuals to specialize in one task rather than knowing and carrying out all the process. This system dates back to the Neolithic era as in communities there were individuals in charge of hunting, others in charge of growing crops, etc.
Also, this system has been widely applied since the Industrial Revolution as in manufacture an individual does not participate in all the process of creating a product but just in one stage. Considering this, the one that is an example of labor is one person add pedals and one adds wheels to a bicycle, as this shows the division of tasks in the process of manufacture that commonly occurs in the division of labor, which is opposite to one individual assembling all the bicycle.
