Answer:
B. Feelings of pride and pleasure as he looks at the final results.
Explanation:
It is a normal human tendency that a person feels good and happy when he receives what he wants even if that involves payment in the form of money. But if that involves a lot of things more than money, which are generally the efforts of the individual in the form of labor and hard work done by himself then such results gives an immense pleasure to the individual.
This develops not only the satisfaction in terms of what you see in the results but also one tends to develop the skills of doing such particular job.
