Why might option b have lone pairs? Wouldn't it look like option a if it had lone pairs?

I believe that option b may have lone pairs because if a lone pair was added to each side of the central atom, the overall shape would appear as depicted and not bent like a.

Option B can have lone pairs since if there are five electron regions with three lone pairs, the lone pairs will reside in the equatorial plane which would create a linear structure. Additionally, if there were 6 electron regions with four lone pairs, the resulting structure will also be linear. Since those two cases exist, there can be lone pairs in the structure.
