Final answer:
The oboe cadenza in the recapitulation is what does NOT occur in the first movement of Beethoven's Symphony No. 5.
Step-by-step explanation:
The correct answer is b. oboe cadenza in the recapitulation. In Beethoven's Symphony No. 5, the first movement known as the Allegro con brio features the famous opening motive, which consists of short-short-short-long notes. This motive is repeated throughout the movement and serves as a unifying theme. The extended coda and the brief recurrence of the scherzo are also present in the first movement of Symphony No. 5.
