- A. Determine if a metabolic disorder exists.
- B. Identify the sex of the fetus.

Choice B is incorrect as determining fetal sex is not the primary purpose of amniocentesis at this gestational age. Choice C is incorrect as identifying abnormal fetal cells is not the main goal of amniocentesis in this scenario.
