(D) Classification + Localisation
This task involves both identifying what object is present in an image and determining its precise location within the image.
Source: Chapter 5, Section 5.2 Computer Vision Tasks
The passage explicitly states: "Classification + Localisation is the task that involves both processes of identifying what object is present in the image and at the same time identifying at what location that object is present." Object Detection (B) also finds locations, but for multiple objects; Classification + Localisation is specifically defined as doing both identification and location for a single object — matching the question exactly.
