I choose A.
A seems the most clear, but still stylish.
B has nicest colors with the gradients.
C is fun, but the N looks more like a 2 on its side.
Discussion
I like them all, was leaning towards B, but A is clear and I like that ostrich better..
A. I liked C at first, but the N started to look weird and the ostrich looks like a duck. The block idea is cool, though.
The ostrich on A isn't super obvious other than the legs. Those are great. The neck and head need to be more ostrichy.
Great feedback. Most like C, but same feedback around the N.
Thinking to go with C, fix the N and B, and flatten the nostrich
