<h3>d. extraneous.</h3>
Explanation:
Extraneous variables are variables which occur unintentionally while doing a research. When a researcher tries to find if an independent variable has an effect on a dependent variable, they may be chances that unexpected variable might occur which may affect the results of the research.
