All of the listed aspects can result in an unrepresentative sample. Convenience sampling may result in a biased sample that is not representative of the population. Poor response rates can lead to non-response bias, where those who do not respond are systematically different from those who do. High experimental mortality for some groups and not others can also result in a biased sample, where the survivors are not representative of the original sample. Therefore, all the options are the best choices.
