Why this question matters

This question is drawn from the “A Modern, Thriving Society” section of the official Home Office handbook. Topics from this chapter make up a significant portion of the 24 questions in the real exam, so being able to answer this one comfortably is a small but real step towards passing on the day.

The accepted answer is C: “John MacLeod”. Memorise the underlying fact rather than the option letter — the order of options changes between attempts, and the real exam may rephrase the question.
