The correct answer is

B and C only

Savyabhichara Hetvabhasa (Irregular/Wandering Middle) occurs when the hetu (reason) is too wide — it is found in both sapaksha (similar cases) and vipaksha (dissimilar cases), making the inference unreliable.
B: 'Sound is eternal because it is audible' — 'audible' is found in both eternal and non-eternal things, so the hetu wanders, giving Savyabhichara.
C: 'Sound is eternal because it is produced' — 'produced' also wanders across both categories here, giving Savyabhichara.
A: 'Sound is a quality because it is visible' — sound is not visible; the hetu is itself unestablished, so this is Asiddha Hetvabhasa (unproved reason), not Savyabhichara.
The answer is B and C only.
