The change in the inventory of a firm is treated as an investment. What are the major categories of investment?

(A) Investment Expenditure.
(B) Autonomous Investment.
(C) Fixed Business Investment.
(D) Residential Investment.

Choose the correct answer from the options given below:

(B), (C) and (D) only

The correct answer is Option (4) → (B), (C) and (D) only

Note: The given answer is as per NTA answer key. However, the answer of this question should be Option 1: (A), (C) and (D) only as per NCERT. NCERT clearly classifies investment into three major categories: investment expenditure (which includes change in inventories), fixed business investment, and residential investment. It does not list autonomous investment as a category

The relevant portion of NCERT is reproduced below:

NCERT : "Inventories are treated as capital. Addition to the stock of capital of a firm is known as investment. Therefore, change in the inventory of a firm is treated as investment. There can be three major categories of investment. First is the rise in the value of inventories of a firm over a year which is treated as investment expenditure undertaken by the firm. The second category of investment is the fixed business investment, which is defined as the addition to the machinery, factory buildings and equipment employed by the firms. The last category of investment is the residential investment, which refers to the addition of housing facilities."
