True.

Explanation:

The given statement asserts a true claim as it rightly defines Mill's concept of 'Utilitarianism'. Mill describes that 'utility' as the outcome of a righteous action which promotes pleasure and happiness for an individual. He asserts that the proportion or amount of righteous conduct determines the proportion or amount of happiness or goodness of a character it promotes while the amount of wrong categorizes the proportion of unhappiness promoted by it. Thus, these good actions act as a moral limitation to ensure one's happiness which is the only desirable thing according to Mill. Therefore, the statement is true.
