The figure shows triangle MNO and some of its transformed images on a coordinate grid: A coordinate grid is shown from positive 8 to negative 8 on the x-axis and from positive 8 to negative 8 on the y-axis. A triangle labeled MNO is shown on ordered pair 2, 1 and 2, 4 and 4, 1. Another triangle labeled image D is shown on ordered pair 2, negative 1 and 2, negative 4 and 4, negative 1. Another triangle labeled image C is shown on ordered pair negative 2, negative 1 and negative 2, negative 4 and negative 4, negative 1. Another triangle labeled image B is shown on ordered pair negative 6, 1 and negative 6, 4 and negative 4, 1. Another triangle labeled image A is shown on ordered pair negative 2, 1 and negative 2, 4 and negative 4, 1.

Which of the four triangles was formed by a translation of triangle MNO?
