**b. Identical
**
Identical twins as a matter of fact. Identical twins are also called monozygotic babies. They came from one independent egg cell which was fertilized and then develops to become into two separate embryos. In the cases which can specifically involve interaction between these two embryos is monoamniotic twins which share the same amniotic sac and conjoined twins which can cause direct contact from their bodies. These types of identical twins have a higher change of contact and interaction between each other in the womb.
Identical twins are more likely to interact in the womb compared to non-identical twins due to sharing the same amniotic sac. This shared environment allows for physical contact and movement interaction. Non-identical twins develop separately and have limited interaction opportunities.
