Explanation:
The answer for your question is the option "C" dramatic advancement in medical treatments. Because of the inventions of new medical treatements the people are getting a good treatment for their medical issues. In the past people faced many diseases and viruses which lead to destruction and loss of many human lives because of no cure.
Let me give you a gist, in the mid 1300's Plague attacked which was cured by the discovery of Plague Vaccine which targeted the bacteria called 'Yersinia pestis' which was invented by Alexandre Yersin.
In 1775, Small Pox occured which was also called as Measles took many lives until the discovery of a vaccine for it named ACAM2000, and it was dicovered by Edward Jenner in 1796. Which saved many lives.
In 1852, Cholera occured which killed many people until Jaime Ferran discovered a vaccine for cholera 'Vaxchora' ( modern name ).
And now in 2020 we all are facing risk of death due the occurence of a well known virus, guess what " Corona virus" . It is also danger until a vaccine is found. More over there is a vaccine created in a Russian university named Sechenov university which completely clinical trials.
As you can see as the years increase there are new medical problems arriving but in the modern era there are solutions discovered for the cure of them. So as the years passed the medical treatments are also increased to high possibilities for the cure of them.
You may get a doubt, why only this option because due to the development of medical treatment only old people survive for longer periods, and the mortality of imfants also have reduced. Hence proved that if medical treatments are developed then there would be no drastic loss of life.
