Answer:
B. not accurately defined by any of these statements.
Step-by-step explanation:
An inferior good is defined as one whose the quantity demanded decreases as the income of its consumers increases and vice versa.
Option A is incorrect because the income elasticity for inferior goods is negative and therefore, as the income of the consumers increases, the demand curve shifts to the left.
Option C is incorrect because an inferior good does not necessarily mean a fake good. A good can be inferior but yet meet all the standards for approval by the FDA.
Option D is incorrect. The price and quantity demand for inferior goods, just like normal goods do not vary directly. This is only applicable to luxurious goods.
None of the statements in A, C, and D accurately defined an inferior goods.
Hence, the correct option is B.
