Stimulus is something that can evoke a physiological response, it can be in or external.
The total number of deaths in a population due to a disease is the option(b) i.e, mortality rate.
A mortality rate of 9.5 (out of 1,000) in a population of 1,000 would represent 9.5 deaths per year in that entire population or 0.95% of the total. Mortality rates are commonly reported in units of deaths per 1,000 people per year.
The mortality rate is calculated by dividing the total number of deaths in a given area and year by the total population of that area. It is as easy as dividing D by P. D is the total number of fatalities, and P is the local population.
Excess mortality is the term used to describe when an event or illness results in more fatalities than anticipated. A condition that results in excess mortality is COVID-19. Data indicates that COVID-19 caused 50% more deaths than were anticipated in some severely affected countries over a specific time span.
