Final answer:
A laceration is an open wound with torn tissue and jagged edges caused by a sharp object or trauma.
Step-by-step explanation:
The correct answer is A) Laceration. A laceration is an open wound with torn tissue and jagged edges caused by a sharp object or trauma. It is different from an abrasion (superficial scrape of the skin), an incision (a clean, deliberate cut made by a sharp object), or an avulsion (when a piece of tissue is completely torn away from its normal location).
