1) Nonresponse bias : Non response bias is introduced bias in statistics when respondents differ from non respondents. In other words, it will throw your results off or invalidate them completely. It can also result in higher variances for the estimates, as the sample size you end up with is smaller than the one you originally had in mind.
2) Self-interest bias :The self-serving bias is people's tendency to attribute positive events to their own character but attribute negative events to external factors. It's a common type of cognitive bias that has been extensively studied in social psychology.
3) Social acceptability bias : In social science research, social desirability bias (or social acceptability bias)is a type of response bias that is the tendency of survey respondents to answer questions in a manner that will be viewed favorably by others.
4) Voluntary response bias : In survey sampling, voluntary response bias occurs when sample members are self-selected volunteers, as in voluntary samples . An example would be call-in radio shows that solicit audience participation in surveys on controversial topics (abortion, affirmative action, gun control, etc.).
so the answer will be self interest bias.
