In the context of manual extraction of feature data, the correct choice is based on understanding the methods that are traditionally employed in extracting two-dimensional representations of geographic features from imagery. Stereo imagery and mono imagery are both techniques used in manual extraction. Stereo imagery utilizes pairs of images taken from slightly different angles to create a three-dimensional view, allowing for the identification of features through depth perception. Mono imagery refers to single images, where features can still be delineated albeit with less spatial information compared to stereo imagery.

Hand-drawn vector delineations fit well into the manual extraction category, as this method involves physically sketching or tracing features directly onto a map or digital interface based on visual inspection of the imagery.

In contrast, LIDAR (Light Detection and Ranging) is a remote sensing technology that collects data through laser light pulses. It generates three-dimensional information about the surface of the Earth, but it is generally processed through automated or semi-automated techniques rather than being classified as a manual extraction method. The nature of LIDAR data collection and processing makes it distinct from the manual approaches represented by the other options. Thus, this is why LIDAR is not included in the methods of manual extraction of feature data.
