a. egretta thula and platalea ajaja
b. pituophis melanoleucus and thamnophis proximus
c. nerodia sipedon and nerodia fasciata
d. eudocimus albus and ardea albus

Explanation:

In biological classification, organisms with the same genus are more closely related. Here, Nerodia sipedon and Nerodia fasciata share the genus Nerodia, while in other options (like A: different genera Egretta and Platalea; B: different genera Pituophis and Thamnophis; D: different genera Eudocimus and Ardea), the organisms have different genera. So the pair in option C is most closely related.

Answer:

C. Nerodia sipedon and Nerodia fasciata
