Step 1: Identify standard autopsy incisions. Primary incisions are the initial cuts made to open the body cavities for examination. The most common types are:
- I-shaped incision (D): A single vertical cut from the neck to the pubic bone.
- Y-shaped incision (B): Incisions from each shoulder meeting at the sternum, then proceeding down to the pubic bone as a single cut. This is the most common method.
- Modified-Y shaped incision (C): A variation of the Y-incision.
Step 2: Identify non-standard or situational incisions.
- U-shaped incision (A): This is not a standard primary incision for a full autopsy.
- T-shaped incision (E): This is also not a standard primary incision.
Step 3: Conclude. Based on standard autopsy procedures, the Y-shaped, I-shaped, and Modified-Y shaped incisions are primary types. The U-shaped and T-shaped incisions are not. Therefore, A and E are the correct answers.
