Which of the Following Best Captures the Procedure That Bentham

Which of the following best captures the procedure that Bentham describes for calculating the total amount of pleasure or pain produced by an action?

A) Calculate the intensity, duration, certainty, propinquity, fecundity, purity, and extent of the action for each person affected by it and then subtract the total amount of pain produced by the action.
B) For each person affected by the action, calculate the value of all of the pleasures the action will cause for that person in the long run and subtract the value of all of the pains it will cause for that person in the long run, and then add up the resulting values from each person affected.
C) Calculate how much pleasure the action will cause for the person performing it, including both immediate pleasures and pleasures that will occur later, and then subtract from that the total amount of pain that the action will cause for the person performing it, including both immediate pains and pains that will occur later.
D) For each person affected by the action, calculate the value of the pleasures that will be produced immediately, ignoring uncertain or distant pleasures, as well as the value of the pains that will be produced immediately, ignoring uncertain or distant pains, and then add up the resulting values from each person affected.
