Analyze the controversy surrounding biofeedback

The effectiveness of biofeedback is debated because it is difficult to design rigorous, double-blind controlled studies to test it objectively, as participants are actively aware of the feedback they receive.

Evaluate the given options

• Option A and Option C describe positive attributes (no side/negative effects), which would not cause controversy regarding its effectiveness.
• Option D is a minor practical issue, not the primary reason for scientific controversy regarding its clinical efficacy.
• Option B directly addresses the scientific challenge of testing and proving its effectiveness objectively.
