Which combination of clinical signs would most strongly suggest chronic insufficient protein intake?

• A. Generalized edema, recurrent infections, delayed wound healing, and muscle wasting due to loss of structural and immune proteins
• B. Improved lean mass retention while subcutaneous fat increases markedly, because protein deficiency preferentially shunts energy into adipose depots
• C. Hyperactivity, excessive hair growth, and sudden improvements in wound healing because low protein triggers compensatory overproduction of growth factors
• D. Increased bone density, hypertension from excessive oncotic pressure, and reduced infection rates due to increased mobilization of immune resources
