Explanation:

- A company: Entities like companies are often considered "persons" in legal contexts. This allows them to take part in legal actions, akin to natural persons.

- An official receiver: An official receiver plays a specific role in insolvency proceedings. They act as a liquidator or trustee. This role can be seen as an extension of personal legal responsibilities.

- Both (A) and (B): This option considers both a company and an official receiver as "persons" under Order 33, Rule 1, recognizing their involvement in legal systems.

The correct answer is: Both (A) and (B)
