Answer 1

400 randomly chosen employees from the list of all employees.

Reason: a large random sample from the entire employee list is most likely to be representative and reduce selection bias. The other options are biased or too small to generalize (one per department may misrepresent department sizes; all females or all long‑tenure employees are not representative).
