Answer:
B. not accurately defined by any of these statements.
Explanation:
An inferior good is defined as one whose the quantity demanded decreases as the income of its consumers increases and vice versa.
<em>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.</em>
<em>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.</em>
<em>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.</em>
None of the statements in A, C, and D accurately defined an inferior goods.
Hence, the correct option is B.
