Hi! I’m pretty sure the answer is B.
If we draw the lewis structure, we can see that all Cl
atoms are all connected to the B atom. Now Cl atoms has 7 electrons each on its
outermost shell while B can donate 3 electrons. So by octet rule, each Cl will
gain 1 electron each from the B atom. From the Lewis structure, we can see that
there are actually No Lone pairs on the central atom.
