The phrase "should have" is the correct choice because it indicates a recommendation or expectation about something that was possible or appropriate in the past but did not happen. In this context, it suggests that the team missed an opportunity or did not choose an option that was advisable.

Using "should have" expresses a sense of obligation or desirability linked to past actions. This construction follows standard English grammar, making it clear that the choice was appropriate at that time but ultimately wasn't made.

The other phrases do not convey the same meaning and might be considered incorrect or informal. "Should" alone suggests a current obligation but lacks the past emphasis. "Should uv" is not standard English and could lead to confusion. "No change" implies that the original text is already correct, but given the need for clarity regarding past decision-making, "should have" is the more precise expression needed in this situation.
