Final Answer :
A
Explanation :
In stratified random sampling, the population is divided into strata based on certain characteristics and then a random sample is taken from each stratum. Within each stratum, elements are randomly selected to form the final sample, rather than taking all elements within a stratum or randomly selecting elements from the entire population. Choice A accurately describes this process.
