The correct answer is option 'C' - The Charter Act of 1833.

Explanation:
The East India Company was a British company that played a significant role in the colonization and administration of India during the British Raj. It was primarily involved in commercial activities, including trade, investment, and governance.

1. The Charter Act of 1793:
- This act was passed by the British Parliament to regulate the activities of the East India Company.
- It extended the Company's monopoly on trade with India for another 20 years.
- It also introduced some reforms in the Company's administration and increased parliamentary control over its affairs.
- However, it did not put an end to the commercial activities of the East India Company.

2. The Charter Act of 1813:
- This act was another attempt by the British Parliament to regulate the activities of the East India Company.
- It ended the Company's monopoly on trade with India, allowing private British traders to enter the Indian market.
- It also introduced some social and educational reforms in India.
- However, it did not put an end to the commercial activities of the East India Company.

3. The Charter Act of 1833:
- This act was a major turning point in the history of the East India Company.
- It abolished the Company's monopoly on trade with India completely.
- It transferred the power of governance from the Company to the British Crown, establishing direct British rule in India.
- It initiated several administrative and judicial reforms in India.
- This act effectively put an end to the commercial activities of the East India Company.

4. The Charter Act of 1853:
- This act further reformed the governance of India under British rule.
- It introduced several administrative and legal changes.
- However, it did not have any direct impact on the commercial activities of the East India Company since those activities had already been abolished by the Charter Act of 1833.

In conclusion, the commercial activities of the East India Company were finally put to an end by the Charter Act of 1833, which abolished the Company's monopoly on trade with India and transferred the power of governance to the British Crown.
