Well, I picked a weird way to do this but well it was a short approach
I thought of the girls as sides of a polygon, and a handshake as a diagonal.
Number of diagonal in a n-sided polygon is n(n-3)/2
Number of handshakes -> 6(3)/2 = 9
Hence D.
P.S.
Look what GMAT does to you, m picturing girls as "sides of a polygon"!!...Sigh...
i will surely use this method for the circular/ 'standing in circle' and condition questions. Pretty insightful, thank you!
