The converse of the statement "If it is red, then it is a color" is "If it is a color, then it is red."
To find a counterexample for this converse, we need to identify a situation where something is a color but is not red.
Among the options provided:
A. Blue is a color. (This is a valid counterexample, as blue is a color that is not red.) B. Red is also a flavor of Gatorade. (This does not address the converse.) C. Red is not a color. (This is incorrect; red is a color.) D. There is no counterexample, because the converse is also true. (This is incorrect since the converse is not necessarily true.)
Therefore, the best choice for a counterexample to the converse statement is:
A. blue is a color.
