The correct answer is "sad." In music theory, a minor key is typically associated with creating a sad or melancholic mood in a composition. To determine the mood of a piece of music, you can listen to the tonality, chord progressions, and melodies used in the composition. In this case, the use of minor scales and chords often contributes to a somber or melancholic feeling. Additionally, the timbre, dynamics, and tempo of the music can also play a role in establishing the overall mood.
