Correct option is A
 
  
 The correct sequence for computing income tax liability is as follows:
  
 1. 
  Income under different heads (A) – Income tax is calculated based on five heads of income:
  
 · 
  Salary 
  
 · 
  House property 
  
 · 
  Profits and gains from business or profession 
  
 · 
  Capital gains 
  
 · 
  Other sources 
  
 2. 
  Adjustment of losses (C) – Losses from previous years or the current year (such as business loss or capital loss) are adjusted before computing the total taxable income.
  
 3. 
  Deduction from Gross Total Income (B) – Certain deductions are allowed under 
  Section 80C to 80U (e.g., life insurance premiums, provident fund contributions, medical expenses).
  
 4. 
  Rounding off (D) – As per 
  Section 288A and 288B of the Income Tax Act, final income and tax payable are rounded off to the nearest multiple of 10.
  
 Since the correct order is 
  A → C → B → D, the correct answer is 
  (a) A, C, B, D.
