Why may the results of a school survey be biased if responses are accepted only online?

Answer and explanation

Correct answer: Opinions of people without digital access may be excluded

The governing concept is sampling bias caused by unequal access. If a school survey accepts answers only online, people without reliable devices, internet service, or digital skills may be unable to participate. Their views are then missing, so the respondents may not represent the whole school community. Option C is correct; online answers are not always wrong, and the other choices do not explain how the sample becomes unbalanced.
