Answer 1

Correct option is (c) Release of enzymes and increased of tissue pressure

The explanation is: The pain is due to local release of enzymes and increased tissue pressure. Bradykinin is the most important pain mediator in an inflammation reaction. The redness and heat is due to the local blood vessel dilation. The swelling is due to the influx of plasma proteins and phagocytic cells into the tissue spaces. These are the four signs of inflammation which can be seen in a human body.
