Did the t. rex have an amniotic egg?

a. probably not because their is no history of closely related animals having an amniotic egg.

b. it is quite likely because lots of animals in the past have had amniotic eggs, so the t. rex probably did too.

c. it is quite likely because both the caiman and parrot have had amniotic eggs and they share recent common ancestor with the t. rex.

d. probably not because the t. rex is no longer living.
