If a controlled variable cannot be kept perfectly constant what is the best scientific step?

Answer and explanation

Correct answer: Measure and record it while keeping its variation small

The governing principle is transparent control of experimental limitations. If a controlled variable cannot remain perfectly constant, the researcher should measure and record it, keep its variation as small as practicable, and consider its possible influence when interpreting results. Hence, option B is correct. Ignoring the variation hides a possible source of bias, while relabelling the variable or deleting all results does not improve the investigation.
