Verified step by step guidance

Step 1: Understand the definitions of the terms provided in the options. A laceration refers to a jagged or irregular tear in the skin. A contusion is a bruise caused by blunt trauma, resulting in damage to blood vessels under the skin. An abrasion is a superficial scraping or wearing away of the skin. An incision is a clean, smooth cut through the skin, often made intentionally during surgical procedures.

Step 2: Analyze the characteristics of the injury described in the problem. The key descriptor is 'clean, smooth cut through the skin,' which matches the definition of an incision.

Step 3: Compare the injury description to the definitions of the terms. Eliminate options that do not match the description. For example, a laceration is jagged, a contusion involves bruising, and an abrasion is superficial scraping, none of which fit the description of a clean, smooth cut.

Step 4: Confirm that the term 'incision' aligns with the description provided in the problem. Incisions are typically clean and smooth, often made intentionally with a sharp instrument.

Step 5: Conclude that the correct answer is 'incision,' as it is the term that best matches the description of the injury provided in the problem.
