Nematocin Appears to Be a Homolog of Vasopressin/oxytocin Because

Nematocin appears to be a homolog of vasopressin/oxytocin because:

A) its receptors are most closely related to mammalian vasopressin and oxytocin receptors.
B) its precursor protein shares conserved structures with those of vasopressin and oxytocin.
C) its mature form shares structural features with vasopressin and oxytocin, particularly the disulfide bond between the first and sixth amino acids.
D) it is necessary for normal reproductive behaviors.
E) All of the above
