Which of the following statements best describe the textbook narrative on moral persuasion?

A) Moral persuasion is one way to reduce energy consumption, but such thing it is not utility maximizing.
B) Moral persuasion could reduce energy consumption and could enter in people's utility functions.
C) Highlighting the inherent moral obligation to save the environment has been demonstrated to have a weak effect on the reduction of energy consumption.
D) It is difficult to quantify the reduction in energy consumption caused by a raising of moral obligation.

The textbook narrative suggests that moral persuasion can enter into people's utility functions and therefore have an impact on reducing energy consumption. Option A is incorrect because the textbook does not say that moral persuasion is not utility maximizing. Option C is incorrect because the textbook acknowledges the weak effect of highlighting moral obligation, but it does not suggest that it has no effect. Option D is also incorrect because the textbook acknowledges that it is difficult to quantify the reduction in energy consumption caused by moral obligation, but it does not suggest that no reduction occurs.
