Final Answer :
E
Explanation :
All options are correct. Tiktaalik is known for having wrist bones and a neck, which are significant in the study of vertebrate evolution, particularly in understanding the transition from aquatic to terrestrial life. Eusthenopteron is noted for having a stout bone extending from the shoulder girdle, a feature that is important in the context of the evolution of limb structure.
