Explanation:

Identify the musical section and its characteristics

The question describes characteristics of a specific section within a sonata-form movement. All four options agree that "the opening theme is fragmented and transformed," which is the defining melodic feature of the Sonata Form Development section.

Analyze harmonic stability in the development section

Using the Sonata Form Development knowledge point

• The development section is characterized by rapid modulations through various keys, making the music harmonically unstable.
• This instability builds dramatic tension before resolving back to the tonic key in the recapitulation.
• Therefore, the correct option must state that the music is harmonically unstable.
