The answer is B. some of the sample data are missing.

This is because out of the 100 students originally sampled by the government agency, only 88 results were taken.

Additionally, we cannot fully take A. as the answer because a non-response error happens when sampling units are not interviewed maybe because they were unavailable or unwilling. So B. is the safer answer.
