Which words in the sentence are the complete gerund phrase?

"Kingfishers build nests by tunneling into the sides of riverbanks."

A. tunneling into the sides of riverbanks
B. by tunneling
C. kingfishers build nests
D. into the sides of riverbanks

I would say A. tunneling into the sides since gerunds contains ing's and it acts as a noun.
I hope this helps!
