Select the Venn diagram that best represents the relationship between the following three classes: Right angle, Obtuse angle and Reflex angle

The correct diagram is the one with three separate circles that do not touch or overlap.
A right angle measures exactly 90°, an obtuse angle lies between 90° and 180°, and a reflex angle lies between 180° and 360°.
These ranges do not overlap, so no angle can belong to two of these classes at once, and none of the classes contains another.
Three mutually exclusive classes are shown by three disjoint circles.
