b. 3 bonds to and a lone pair on oxygen
c. 5 bonds to carbon
d. 3 bonds to carbon

3 bonds to boron
why please and thank you
Actually, I don't like the answers BECAUSE c and d make no sense what-so-ever. What does carbon have to do with the question? As far as that goes, what does oxygen and answer b have to do with the question?
Look up the Lewis structure of BF3 on the internet. B has 3 electrons and it pair with 3 F atoms to make 3 covalent bonds to form BF3. You see there is no lone pair on B so there are only 6 electrons, not eight, around B. So it violates the octet rule.
