b.It is not possible to make a career out of a hobby.
Explanation:
Choosing a career and following through the long process of building this career is not an easy task, it demands a high level of commitment and hard work. However, it is a common misconception that you cannot build a career based on a personal hobby. This not only is false, but also pernicious. A hobby (like carpentry or reading) can very well grow to be a career, and, if, as the saying goes, one loves what one does, then the career in question will not only bring economic sustenance, but, perhaps also self-realization.
