The correct answer is C. The provision of legal advice on wills, while sensitive, is not classified as a 'reserved legal activity' under UK law, which means that it does not strictly require formal legal qualifications or authorisation from legal regulatory bodies. Margaret can offer advice on wills as part of her services without needing specific legal accreditation. It is crucial to note that while giving legal advice on such matters is not regulated, representing a client in court or conducting litigation would require proper authorisation and qualifications, which are beyond Margaret's current capabilities as a financial advisor.

Key Learning Points:

• Reserved vs. Non-Reserved Legal Activities: Understanding the distinction is vital for legal compliance, especially for professionals branching into legal services.

• Regulatory Framework: Familiarity with the Legal Services Act is essential for ensuring that one's practice adheres to legal standards.

• Consumer Protection: While non-reserved legal activities can be performed without formal accreditation, practitioners are still subject to general consumer protection laws, and maintaining professional standards is crucial for credibility and client safety.
