How did she express her sentiment about the test?

The choice indicating that she congratulated someone on passing the test suggests a positive sentiment and an acknowledgment of success. This response implies that she viewed the outcome of the test favorably, likely appreciating the effort and success achieved by the individual who passed. The congratulatory tone reflects a supportive and encouraging attitude, demonstrating that she is happy about the positive result.

In contrast, the other options convey different feelings: criticizing the outcome would indicate dissatisfaction, being indifferent would demonstrate a lack of concern or emotional investment in the result, and expressing disappointment would signal a negative reaction to the test's outcome. Each of these alternatives reflects an emotion or attitude that does not align with a congratulatory sentiment, making the choice of congratulating on passing the test the most accurate representation of a positive expression.
