- C.
23 weeks
- D.

The development of the fetus at 20 weeks includes the formation of distinct facial features, the ability to hear sounds, and the development of organs such as the heart, lungs, and kidneys. Additionally, the fetus would have reached a length of about 6.5 inches and would be more active, with the mother being able to feel its movements.Rate this question:

The correct answer is 14 weeks because at this stage, the embryo/fetus has developed certain characteristics and features that are consistent with a 14-week gestational age. These may include the formation of organs, limbs, and facial features, as well as the presence of distinct gender markers. Additionally, medical professionals can use ultrasound imaging and measurements to determine the age of the embryo/fetus, and these indicators align with the 14-week mark.Rate this question:
