staratified sampling answer

Hi Hemangi sorry i m posting it late, your question was for the genralisibility and representativeness of a sample which type of stratified sampling would we choose?
Any type of stratified sampling can be choosen because we select sample randomly so the sample will be representative for the population and results can be genralised but proportional stratified sampling will be more appropriate because there will be more representative samples because samples will be selected proportioanate to the population and it also reduces errors between strata with respect to the relative numbers selected.
