Point B's coordinates are given as (10, 3). Since the origin and axes are not shown, it's important to consider the symmetry and positions relative to point B. If point A is to have coordinates that are most likely correct in this context of the graph, it would typically be on the same vertical or horizontal line as point B. Given the graph's context of plotting weight gain over time, it makes the most sense for point A to have the same weight (y-coordinate) or the same month (x-coordinate). Options A, C, and E do not align logically with point B based on this graph, leaving option D (-10, 3) as the most likely coordinates for point A.
