**Core Concept**
Tattoo marks are not visible during autopsy due to the destruction of the pigment during the process of decomposition. The visible signs of tattooing can be identified through other means during an autopsy.
**Why the Correct Answer is Right**
The correct method to verify the presence of tattoo marks during autopsy is by examining the lymph nodes, particularly the axillary and inguinal lymph nodes. The tattoo pigment is phagocytosed by the macrophages in the lymph nodes, making them a reliable indicator of the presence of tattoo marks. This phenomenon is due to the body's attempt to remove the foreign substance, and the lymph nodes serve as a filter for the immune system.
