I"ll go with A

1: B|B|= B^2
Clearly B^2 is always >=0
So B|B| >=0
Since |B|>=0, B must be >=0
S0 sufficient

2: |B|+B !=2

So B could be <0,>0,=0

So not sufficient

Hence A

D

Statement 1:
B^2 is +ve.
|B| is +ve.
So, B = +ve SUFF

Statement 2:

Factorials are not defined for negative numbers. So, only value for B is +ve. I know the argument sounds specious. :wink:

Ahhh, my mistake I guess. :oops: It must be |B| + B not equal to 2.

Now it is a sure A
