Final answer:
Advances in Medical Technology and Increased Preventive Measures contribute to the rising cost of healthcare, while Decreased Administrative Costs is not a contributing factor.
Step-by-step explanation:
The rising cost of healthcare is contributed to by several factors. Advances in Medical Technology (a) can lead to increased costs as new technologies and treatments are often expensive to develop and implement. Decreased Administrative Costs (b) can help reduce overall healthcare expenses, but it is not a contributing factor to rising costs. Increased Preventive Measures (c) can also help lower costs in the long run by preventing more expensive treatments later on. Reduced Population Growth (d) can have a minimal impact on rising healthcare costs as a smaller population may lead to decreased demand for healthcare services.
