A & B both look like roosters to me...
Edited to add: I think the best way to tell is for someone to see them in person... I can't tell much from the photos... they may be both pullets, but it's hard with that breed to tell.
Thanks. I can't tell for sure either. I am going to try and post in the EE thread & see what they say. I really want one to be a pullet but doubt it. There was another one that was red & he has gotten the saddle feathers and neck feathers of a cockerel but it was from a different hen. Also my other white one that is a cockerel does not look like these (he's 3 wks older).
