Chemical Bonding And Molecular Structure Question 31

Question: The table shown below gives the bond dissociation energies $ (E_{diss}) $ for single covalent bonds of carbon atoms with element $ A,B,C $ and $ D. $ Which element has the smallest atoms [CBSE PMT 1994]
Bond $ E_{diss},(kJmo{l^{-1}}) $
$ C-A $ 240
$ C-B $ 328
$ C-C $ 276
$ C-D $ 485

Options:

A) A

B) B

C) C
