-likely due to confounding
-not likely due to confoundingNone of above

Answer 1

Likely due to confounding.

Step-by-step explanation:

This outcome can most likely be explained as a consequence of confounding. Confounding refers to a distortion in the measure of association between two variables. This inaccuracy is the consequence of the variable of interest being mixed up with another factor that played a role in the result. In this example, this means that there might be another variable at play that causes this association between eating fruits and vegetables and the risk of developing colon cancer.
