See the answer below.

Work Step by Step

Bond energy increases and bond length decreases with a bigger bond order. For the molecules cited, from tables 8.7 and 8.8, we can see that C$\equiv$C is shorter and has a bigger dissociation enthalpy than the other two, similarly to C=C in relation to C-C.
