The correct option is A intensity
Utility is the satisfaction derived from the consumption of a good or service. It is the intensity of desire for the goods which satisfies the human needs. Utility does not have any relevance with the good or bad and does not get affected with the quality, novelty or uniformity of the commodity, i.e. whether the consumption of any commodity or service will be useful to the consumer or not rather it is effected by the intensity of wants of consumer.
