  F
I didn't place the electrons around each F atom because of spacing problems but there are 8 electrons (4 pairs) around B. Count each shared pair as 1 for B. That is 4. It is in group IIIA and has only three in the elemental state. That gives it one more electron than it started with so that is a -1 charge.
