Correct Option: B. £18,000 Detailed Explanation: To determine how much Mrs. Seri Bepo was earning per month in the United Kingdom, we need to analyze the context provided in the question. The question specifically asks for her monthly earnings, and the options given represent different amounts in British pounds (£) and Nigerian Naira (N).

1. Understanding the Options:
2. A. £5,000: This amount is relatively low for a professional salary in the UK, especially for someone who might be in a managerial or specialized role.
3. B. £18,000: This amount translates to a more substantial annual salary when calculated monthly, making it a reasonable figure for a professional in the UK.
4. C. £3,600: This is a low monthly salary, which may not be reflective of a professional earning in the UK.
5. D. N400,000: This option is in Nigerian Naira, which makes it irrelevant to the question asking for earnings in the UK.
6. Calculating Monthly Earnings:
7. If we consider option B (£18,000), we can break it down to a monthly figure:
   • Annual Salary: £18,000
   • Monthly Salary = Annual Salary / 12 months = £18,000 / 12 = £1,500
8. This monthly figure of £1,500 is a reasonable amount for many professions in the UK, especially for entry-level or mid-level positions.
9. Why Other Options Are Incorrect:
10. Option A (£5,000): While this is a plausible monthly salary, it is significantly lower than what might be expected for a professional role, especially in urban areas where living costs are higher.
11. Option C (£3,600): This amount is also low and does not reflect the typical earnings of a professional in the UK. It may be more suitable for part-time or entry-level positions.
12. Option D (N400,000): This option is in Nigerian Naira, which is not applicable to the question. The question specifically asks for earnings in the UK, and thus any currency other than GBP is irrelevant.
13. Common Pitfalls:
14. Confusing currency: Always ensure you are looking at the correct currency when answering questions about earnings.
15. Misinterpreting the context: Understanding the professional landscape in the UK is crucial to making an informed choice about salary expectations.

Revision Summary:

• Mrs. Seri Bepo's monthly earnings in the UK were £18,000 annually, translating to £1,500 monthly.
• Option B is the most reasonable and relevant choice based on the context of professional salaries in the UK.
• Other options either misrepresent the expected salary or are in the wrong currency.
• Always pay attention to the currency and context when answering financial questions.
