We are told that the sum of the angle measures in a triangle is more than 180°. This means we are woring on a Non-Euclidian geometry.
However, we do not have enough information to determine what kind of geometry we are working with, as for example, both Spherical and Elliptic geometries meet the condition of the sum of the measures of interior angles in a triangle being greater than 180°.
Thus, option D. is the one that best fits the statement.
