Arrange the following sources of revenue of the Central Government in ascending manner in terms of percentage contribution to the total revenues of the Central Government in 2023-24
- AUnion Excise Duty, Custom, Corporation Tax, GST
- BCustom, Union Excise Duty, GST, Corporation Tax
- CCustom, Union Excise Duty, Corporation Tax, GST
- DCustom, GST, Union Excise Duty, Corporation Tax
Explanation
For 2023-24, the Centre's tax receipts in ascending order were: Customs duties (the smallest of the four, roughly ₹2.1 lakh crore), Union Excise Duties (roughly ₹3 lakh crore), GST collections accruing to the Centre, and Corporation Tax (the largest, roughly ₹9.1 lakh crore). Corporation Tax has traditionally been the single largest tax head for the Union government. This gives the ascending order Customs < Union Excise Duty < GST < Corporation Tax, i.e., option B. (The official key's original option D is impossible because it places GST below Union Excise Duty.)
