Answer:

C. 324°

Step-by-step explanation:

We are given that,

The spinner is rotated 180° counter-clockwise about the center and maps J to A.

Since there are 10 sections of the spinner.

So, the angle by each section = [tex]\frac{360}{10}[/tex] = 36°

That is, the angle which maps J to A clockwise is 36°

Then, the angle which maps J to A counter-clockwise = 360° - 36° = 324°

Thus, option C is correct.
