A Correct answer
Explanation

Dimples are indeed caused by the variation in how the facial muscle (zygomaticus major) attaches to the skin. In people with dimples, the muscle splits into two bundles with one attaching directly to the skin, creating a depression when smiling. This is a genetic trait that is actually a dominant genetic characteristic.
