To determine the bare minimum number of users needed to run a successful design test, we should consider the context of usability testing and gathering meaningful feedback.

It is generally accepted in usability testing circles that a minimum of 5 users can uncover about 85% of usability issues. However, the number can be increased based on the complexity of the design and the diversity of users.

Here’s a breakdown of the options:

1. 20 users: This could provide more comprehensive feedback but is more than what's typically necessary for initial tests.
2. 110 users: This is generally excessive for a single round of usability testing.
3. 25 users: Similar to the 20 users, this number is also more than the essential minimum but can be reasonable for certain complex tests.
4. 3 users: This is too few to generate reliable results.
5. None of the above: This suggests that no option represents the true minimum.

Final Answer

The correct answer is None of the above, as the bare minimum to uncover most usability issues is typically around 5 users.
