Step1: Recall symmetric distribution

A symmetric distribution has a shape that is a mirror - image on either side of the center.

Step2: Analyze Option A

The left - hand side of the dot - plot in Option A is not a mirror image of the right - hand side.

Step4: Analyze Option C

The left - hand side and right - hand side of the dot - plot in Option C are not mirror images of each other.

Step5: Analyze Option D

The left - hand side and right - hand side of the dot - plot in Option D are not mirror images of each other.
