The correct order of bond strength starting from the weakest is:
Select one:
N-N, O-O, C-C
C-C, N-N, O-O
C-C, O-O, N-N
O-O, N-N, C-C

Welcome to the forums, rhiannon red. A policy of this forum is that you must show work to receive help.
If you don't know where to start, consider: what is typically different between the ways that carbon, nitrogen, and oxygen bond to other atoms? If that is still not enough of a thought-provoker, do you know why water is bent?

Bond energies are  affected by the presence of lone pairs on the the bonded atoms ...think in this way and try get the answer...
