Which of the following is a source of tax revenue?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Customs.
Customs is a source of tax revenue. Customs duties are taxes imposed on goods imported into or exported out of a country. They are collected by the government to regulate trade, protect domestic industries, and generate revenue. In contrast, penalties are fines for violations, profits are earnings from business activities, and grants are financial aid provided by governments or organizations, which are not considered sources of tax revenue.
