• D. Cardiff became a city (1905), Infirmary established (1837), Public Baths Act (1846), Sanitary Act (1866)

Answer: (A)

Understanding how public health milestones unfold in Cardiff over time helps you see how hospital care, sanitation, and civic status built up in the 19th and early 20th centuries. The infirmary was established in 1837, showing hospital care arriving earliest. The Public Baths Act came in 1846, bringing public bathing facilities as part of improving living conditions. The Sanitary Act of 1866 extended sanitary responsibilities to local authorities, a move forward in public health management. Cardiff became a city in 1905, a later administrative milestone.

Putting these dates in order gives 1837, 1846, 1866, 1905, which matches the chronological sequence. The other sequences misplace dates, such as putting 1846 after 1866 or starting with 1905, which breaks the timeline.
