The statement "All consumption goods are durable in nature" is false.
- Durable Goods:
These are goods that have a long life span, and can be used repeatedly over an extended period of time, such as cars, appliances, and furniture.
- Non-Durable Goods: These are goods that are consumed immediately or within a short period of time, and are used up in a single or few uses, such as food, beverages, and toiletries. While durable goods are part of consumption, many consumption goods are non-durable. For instance, when people purchase groceries or clothing, these items are consumed or used up in a short period.
Therefore, not all consumption goods are durable.

(A) Normal goods | (I) These goods are consumed together |
(B) Inferior goods | (II) Demand for the good decreases as income of the consumer increases |
(C) Substitute goods | (III) These goods are used in place of each other |
(D) Complementary goods | (IV) Demand for the good increases as income of consumer increases |
A compound (A) with molecular formula $C_4H_9I$ which is a primary alkyl halide, reacts with alcoholic KOH to give compound (B). Compound (B) reacts with HI to give (C) which is an isomer of (A). When (A) reacts with Na metal in the presence of dry ether, it gives a compound (D), C8H18, which is different from the compound formed when n-butyl iodide reacts with sodium. Write the structures of A, (B), (C) and (D) when (A) reacts with alcoholic KOH.
