Explanation:
A stratified sample is a type of probability sample where the population is divided into different groups or strata, and then randomly selected sub-samples from each stratum are taken to form the total sample. This method ensures that each stratum is represented in the final sample, allowing for more precise analysis and estimation of population parameters.		 A
