Which type of prints result from body residues left behind that are generally invisible to the naked eye?

Latent prints are the correct choice because they are formed from the natural oils and sweat secreted by skin, leaving behind residues that are generally invisible to the naked eye. These prints require specialized techniques, such as dusting with powders or using chemical developers, to become visible for examination.

In contrast, plastic prints are three-dimensional impressions left in a soft material, like wax or clay, and can be directly seen or manipulated. Patent prints, also known as visible prints, are those that are readily identifiable without any enhancement, such as inked prints, which are clearly visible as they are left in a medium that contrasts with the surface. The key distinction with latent prints is their invisibility at first, which necessitates additional processing techniques to reveal them for forensic analysis.
