The correct answer is B ) Professional competence.
The quality of taking any job seriously and being accountable to work and the habit of arriving workplace on time indicates professional competence.
When we are talking about professional competence, what we mean is that the individual has acknowledged his level of responsibility, commitment, and he is aware that he has to behave in the right way to earn trust in the workplace. He has to be accountable.
Professional competence means that there will be no excuses for being late to a meeting, for making non-sense excuses, because a true professional do things right all the time.
