These can be ranked on the basis of their bond energies, more stable bond having the high bond dissociation energy.
Order is as follow :
C-F(485kj/mol)>Si-O (452)>C-O (358.5)> C-C (346)> C-Si(317) >C-N(305).
In the bracket, the bond dissociation energie of the corresponding compound is given.which is in KJ/mol.

with my understanding of hydrogen bonding, it can only happen
between N, O, or F. So answers B, C, and E seem like the best
choice.
