✅ ANSWER: A
According to Marshall, the basis of consumer surplus is Law of diminishing MU. As per the law, as we purchase more of a commodity, its marginal utility reduces. Since the price is fixed, for all units of the goods we purchase, we get extra utility. This extra utility is consumer surplus.
