Correct Answer: The tuition fees paid by students

Solution : The correct answer is (b) The tuition fees paid by students

The "cost of education" encompasses various expenses associated with acquiring knowledge and skills. This includes the tuition fees paid by students to educational institutions as well as the cost of textbooks, study materials, and other resources required for learning. These direct costs are borne by individuals or their families when pursuing education. However, it's worth noting that the cost of education can also include indirect costs such as transportation, accommodation, and other related expenses. The salary paid to teachers and the market value of educational institutions are not typically considered as part of the direct cost of education.
