Narmeen is viewing the board in the classroom. She knows that the board is located far away because the view from her left eye is slightly different than the view from her right eye. Her ability to judge the distance of the board is due to which depth cue:

retinal disparity

Explanation:

Retinal disparity can be described as a type of cue which people use to make observations about the depth of something. In retinal disparity, an object is measured through both eyes and the difference between the view that each eye perceives depicts the depth cue of the particular individual. Both the eyes will have different angles of the object which is being studied or which is under observation.
