An economist would conclude that the student enrolled in the additional course because they have determined that the expected marginal benefit of taking the course exceeds the expected marginal cost. This decision is in line with the rational choice theory, which states that individuals make choices based on a cost-benefit analysis. The opportunity costs of taking the course are not mentioned in the question, so it cannot be determined whether the student considered them or not. Therefore, the best choice would be D.
