Belinda Sellers · Answer 1

B. eating honey

Explanation:

a confounding variable is eating honey for breakfast. This is an extraneous or extra variable in the experiment, which can adversely affect the effects of oatmeal for breakfast. Introduction of honey as an extra variable can ruin an experiment and the expected results, as apart from oatmeal, honey will also produce it's effects, which will wrongly be attributed to oatmeal.
