Ans. D

Explanation:

Difference between ante-mortem and post-mortem wounds:
 

Trait

Ante-mortem wounds

Post-mortem wounds

Edges:

Swollen, everted, retracted, and wound gapes

Edges do not gap, but are closely approximated

Haemorrhage:

Abundant and usually arterial

Slight or more and venous

Spurting:

Signs of spurting of arterial blood on the body, clothing or in its vicinity present

No spurting of blood

Extravasation:

Staining of the edges of the wound and extravasation in neighbouring subcutaneous and interstitial tissues which cannot be removed by washing

Edges and cellular tissues are not deeply stained. The stain can be removed by washing

Coagulation:

Firmly coagulated blood in wounds and tissues

No clotting or soft clot

Vital reaction:

Present

Absent

Enzyme histochemistry:

Increased enzyme activity

Diminished or no enzyme activity
