Explanation:

Let's break down each pair:

- A NDPfc (i) national income:

- NDPfc stands for Net Domestic Product at factor cost.

- It is equal to GDPfc minus depreciation.

- It does not exactly equate to national income, as national income is usually represented by NNPfc.

- B NDPmp (ii) GDPfc - depreciation +NIT:

- NDPmp stands for Net Domestic Product at market price.

- To calculate it, you subtract depreciation from GDPmp.

- Net Indirect Taxes (NIT) are not added; rather, NIT are calculated by removing subsidies and adding taxes to the factor cost.

- C NNPfc (iii) Domestic income:

- NNPfc stands for Net National Product at factor cost.

- It represents national income, not just domestic income.

- D GNPfc (iv) NDPmp + depreciation +NIT + NFYA:

- GNPfc is Gross National Product at factor cost.

- It accounts for Net Factor Income from Abroad (NFYA), but this expression is an incomplete calculation for GNPfc.

Based on these explanations, the incorrect pair is 2, B-(ii).
