What is Sagittarius B, the star forming region, so close to the Black Hole at Sagittarius A, doing? The star forming region is only 10 light years away from the Black hole at the galactic center. What is the mechanism and reason for this formation so close to a Black Hole that represents is destruction?

So far, I haven't been able to find any reference for a star-forming region 10 ly from Sagittarius A. The largest molecular cloud is Sagittarius B2, which is ~100 parsecs from the center of the galaxy (over 300 ly).
I also don't know why you assume that the BH at the center of the galaxy would represent its destruction. Even at 10 ly distance, the gravitational pull from the BH would be less than 1/1000 of the pull the Sun has on the Earth. Tidal forces, which fall of by the cube of the distance, would also not be significant. At 300 ly, the gravitational pull would fall of by a factor of 900 and the tidal forces by a factor of 270000.
"Close" is a relative term. 300 ly is "close" to the center of the galaxy compared to the overall size of the galaxy, but really isn't "close" in terms of separation from Sagittarius A in terms of gravitational effects from the BH.

Tricky
Sounds too close for comfort
