Answer:

D. Aneuploidy

This means that the fetus was monosomic (aneuploid) for a chromosome.

autocrine: a cell signals to itself, releasing a ligand that binds to receptors on its own surface 

endocrine:When cells need to transmit signals over long distances, they often use the circulatory system as a distribution network for the messages they send. 

synaptic: nerve cells transmit signals. The junction between two nerve cells where signal transmission occurs.
