Based on the definition of supplementary angles and linear pair, a counterexample to the statement is: option B.
<h3>What are Supplementary Angles?</h3>
If two angles add up to give 180 degrees, they are regarded as supplementary angles.
<h3>What is a Linear Pair?</h3>
A linear pair is two adjacent angles that share a common side on a straight line, and have a sum of 180 degrees. Linear pair angles are supplementary angles.
In the image given, figure D is a perfect example of a linear pair that are supplementary.
However, in figure B, we have two angles that are not adjacent angles on a straight line but are supplementary angles.
Therefore, a counterexample to the statement is: option B.
