The correct response is:
**It allows for more reliable results by reducing bias.**
Random assignment is crucial in experimental design because it helps ensure that any differences observed between groups can be attributed to the treatment rather than other variables. This reduces systematic bias and helps create groups that are comparable at the outset of the experiment.
