Dear student ,
In cyano group, C is triply Bonded to N, IN THIS STRUCTURE, THE C of cyano group is seen to be attached to 3 bonds from N and 3 bonds from C , which makes up atotal of 6 bonds to C atom of cyano group, which is highly unstable, because it is disrupting the complete octet rule for Carbon atom.
Hence ‘g’ bond wont exist, it is easy to break
Bond ‘a’ WILL BE STRONGEST.
