question about tsumego (GoChild)


I have a question about this go problem:
Dong-Dong grouping > (1) ~10k_6350 > (3) 30k~25k > (5) > 2945
Found at GoChild:
http://gochild2009.appspot.com/?locale=en_US

The solution given is to move at B9 as black, but I'm having trouble
understanding
why that would be better than say a move at B8 for black.
Can someone explain why black is supposed to play at B9 and not at B8?
Kind regards and thanks in advance for any suggestions, Niek
