Right answer is (b) Trypsin
To elaborate: For bacterial infections, lysozyme is used as antibiotic as it has the capacity to hydrolyze bacterial cell wall. In the same way, to treat inflammation, trypsin is used as it has protein hydrolysis capacity. Hyaluronidase hydrolyzes hyaluronate and is used in the treatment and diagnosis of a heart attack. Collagenase hydrolyzes collagen and is used in the treatment of skin ulcers.
