The artist, known for her _______ interpretations of classical themes, often incorporated modern industrial materials into her sculptures, much to the chagrin of traditionalists.

✓ Correct Answer: Option B

The context 'much to the chagrin of traditionalists' indicates the artist challenges established norms. 'Iconoclastic' means attacking cherished beliefs or institutions, fitting this description perfectly. 'Prosaic' means dull, 'reverent' means respectful, and 'conventional' means ordinary, none of which fit the contrast.
