Final answer:
The most common form of androgen insensitivity syndrome occurs in individuals with XY chromosomes because of a mutation that causes their bodies not to respond to male sex hormones.
Step-by-step explanation:
Individuals with the most common form of androgen insensitivity syndrome have the XY sex chromosomes. Androgen insensitivity syndrome is a condition caused by a mutation in the Androgen Receptor (AR) gene located on the X chromosome. Despite being genetically male with one X and one Y chromosome (XY), individuals with this condition develop and are raised as females due to their bodies' inability to respond to androgens, which are male sex hormones. This means the correct answer is e) XY.
