The bond dissociation energy of `B-F` in `BF_(3)` is `646 kJ mol^(-1)` whereas that of `C-F` in `CF_(4)` is `515 kJ mol^(-1)`. The correct reason for higher `B-F` bond dissociation energy as compared to that of `C-F` in `CF_(4)` is

Options

A. Sronger `sigmma ` bond between B and F in `BF_(3)` as comnpared to that between C and F in `CF_(4)\
B. Significant `ppi` =p` pi ` interaction between B and F in `BF_(3)` Whereas there is no possibility of such interaction between C and in ``CF_(4)`
C. Lower degree of `ppi` -`ppi` interaction between B and F `BF_(3)` than that bertweeen C and F in `CF_(4)`
D. Smaller size of boron atom as ccompared to that of carbon atom
