To answer this question, we must consider the factors that have contributed to decreased mortality rates in Australia over the last century. The available options highlight improvements in medical technology and access to healthcare.

The correct answer is (A) medical technology, infectious disease, vaccination programs.

Explanation:

1. Medical Technology: Advances in medical technology have significantly contributed to better diagnosis and treatment, particularly of infectious diseases. Breakthroughs in vaccines and antibiotics have drastically reduced mortality rates from previously common diseases.

2. Infectious Diseases: Over the last century, Australia has experienced effective control measures against infectious diseases, primarily due to vaccinations. Diseases that once caused high mortality rates have been effectively managed through public health initiatives and access to vaccinations.

3. Vaccination Programs: The implementation of comprehensive vaccination programs has directly led to the decline in deaths caused by infectious diseases. This highlights the importance of access to healthcare solutions that prevent outbreaks and promote public health.

In conclusion, option (A) best encapsulates the reasons behind the decreased mortality rates in Australia.
