Answer:
B. Response Bias
explanation:
Response Bias occurs when the respondent inadequately or falsely respond to a question. This is very common when carrying out well structure questionnaire/survey or interviews. Respondents tends to give answers that are "socially acceptable" like what is expected of rather than what really is.
The response bias is also dependent on who is administering the survey. In this case, the survey is been administered by the parent to the respondent who are their children. The children may not want to give answers that are not in the "liking" of their parents or that are not accepted by their parents or may be hiding a few information that they don't want to tell their parents, so they end up giving false information.
