Sagot :

Trisomy 13, or Patau syndrome, is a syndrome where there is an extra copy of chromosome 13. This causes abnormal development and complex organ defects.

To confirm the diagnosis, a karyotype is done, because it sorts the chromosomes by length, banding pattern, and other characteristics, and allows counting the number of copies of each one.

This means the right answer is C. Karyotype.
